10 Individual Boss Behaviours

Various Behaviours

34 Scripts are Controlling the Enemy Systems in Aircraft Sketch Shooter.

Each Boss has his own Individual Behaviour

Certain Aircraft Behaviours are Randomized to give endless Variation in Movement.

Boss Phase

The Bosses are Seperated in 2 Phases, Phase One starts after Wave Five and Phase Two starts after Wave Ten.

Some Boss Aircrafts will Change in Phase 2

Wave Design

The Incoming Waves

The Player will Encounter in all Airfields Enemies coming Inside, they follow a Path smooth and if they Alive at the End the gonna Repeat and come from the Beginning again.

Endless Waves

We Created a Randomizer that can Generate the Waves automatic.

Weapon System

The Old Weapon Design was very Boring, You had to press Multiple Buttons to activate the Individual Weapons and Collect Ammo through Power Ups.

So we Redesigned the whole Weapon System and added the Laser Weapon.

We Designed the Weapon System so it is simple to Use, Fast and create alot of Visual Effects. The Player can Increase the Strength of each Weapons by collecting more Weapon Power Ups.

When the Player gets hit there is the Chance to loose the Weapons. Chances how the Weapon Power Ups get spawned changes through the entire Game.

All Player Aircraft have their Individual Visuals on all Weapons.

Power Box

Power Ups and Downs

Aircraft Sketch Shooter

Through the Game there are Spawning different Kind of Boxes which the Player can Collect to Boost the own Aircraft, or Activate Handicaps, to Increase the Scores.

Collecting Power Ups and Downs, might Attract additional Enemies once they are Collected.
Power Ups

Increases the Score, Grants Weapons, Life and more.

Power Downs

They might Damage your Aircraft, or call additional Enemies, but they also will Increase your Score

Graphic Style

Bright and Dark Mode with Golden and Red Color Setup

Aircraft Sketch Shooter has a Unique Art Style. The Game itself is 2D and the Artwork is Handdrawn. Everything is Black and White.

We wanted to give the Game a little bit more Variation and thought about how we can bring in some Colors.

After a bit of Research and with the help of coding some Shaders and Unity’s Post Processing we were able to bring up our Own Graphic Settings Menu.

The Player can choose between different Premade Color Sets and Bright and Dark Mode. The Dark Mode also makes the Game a bit more Challenging.

Nighthawk Old – New Sprite

Prototype Old – New Sprite

Over the Time we also increased the Visual Quality of all our Aircraft Sprites. It took along Time to go through the entire Set of Aircrafts and Helicopters to give them a Polish.


To Give the Player some sort of Variation to play the Game we implemented the Challenges. This Special designed Airfields are about Dodge Bullets, Survive as long as possible and more.

Retry System

A Big Gameflow improvement, but also a Big Problem to implement.

It took a while until the Retry System from Aircraft Sketch Shooter was fully working. The Original System never was designed to hold such a System.

The Player can Retry a Airfield 3 Times when he dies at the Boss Waves after Wave 5 and Wave 10

Endless Airfield

The Endless Airfield is designed to never Stop. The Player either has to Exit the Game or Die in order to End this procedural Generated Level.

The Level is always Randomized and with Endless Waves it never Stops running.

Like in all Airfields every 10 Waves there Spawns a Boss Enemy that has to be defeated.

Achievements and Scores

Are Saved Individual for Airfields

There are over 30 Achievements that can be achieved during playing the Game. To encourage Players to play through the Game, they can Achieve, Achievements. Local and Online with Steam.

All Achievements Displayed from Aircraft Sketch Shooter

Local Statistics aswell as Highscores gets saved Individual on each Players Device.

Global Highscore List

We Implemented a Highscore System in Aircraft Sketch Shooter. The Player sends after each Airfield played Data to our Server. A Unique ID gets generated for every Device and Player to identify them in the Database.

Filter List

The Player is able to Filter the Highscore Lists after different criteria.

Once the Selection is done the Highscore List gets Build Up and shows the Individual Highscore aswell as Rank.

On our Website, Visitors can check the Actual Scoreboards of Aircraft Sketch Shooter Live

Difficulty Adjustments

Difficult Settings
Double Life:

The Player can Change the Enemie Aircrafts to the Double amount of Life. The Game gets really Challenging if the Enemies not get Killed Quick Enough

Double Enemies:

The Regular Spawner will Spawn the double Amount of Enemies, the Game gets very Stressfull if this Mode is Activated.

We tried a bunch of Difficult Options, if they fit for the Game and can be Balanced well. Like the Weapon Overheat or the Hill Collision which didn’t make it into the Final Release.

When Weapon Heat was activated every Shot the Player took with his Aircraft, Heated Up the Weapon, the Weapon Heat decreased over Time if the Player stopped Shooting. Once the Weapon was Over Heated the player couldn’t Shot anymore until the Weapon was cooled down.

The System was hard to Balance and didn’t matched to a Fast-Paced Theme since the player were forced to Stop Shooting.

Different Aircrafts

The Player can Choose between 3 Different Aircrafts he can Play with.

Their Movement Speed and Power are different, so Player can Adjust the Difficulty aswell by choosing the Aircraft.


Aircraft Sketch Shooter looks like a relative small Game. But isn’t it Impressive how much Mechanics and Features you can put inside such a Indie Game.

To Combine all those Mechanics and make them work together, thats were making Games become Real and Hard Work.

From the Beginning to the End we Spend more then 1000 Work Hours to come to this Point in the Project were we are able and being about to Release the Game.

Base Sketch Defender – 48 Hours Improve The Game

48 Hours are now Over in the Score Space Game Jam #11

What we have done for our Game Base Sketch Defender the last 24 Hours.

Read Previous Post: Base Sketch Defender – 24 Hours

Make it Dark, The Light System

Visual Cone of the Light System in Base Sketch Defender

The Game itself has no Light. So the Enemies are walking through the Dark.

The Player need to Build and Upgrade Lamp Posts and Towers to get View on the Playfield.

Structure Lights

Every Tower and Structure in Base Sketch Defender has his own Light Setup, some Towers and Structures gain a higher Light Cone and Intensity with Upgrades.

Tower Range

The Light Cone also Visualize the Range of each Towers.

Range can be Upgraded at various Towers and Structures.

Individual Bullets

Each Tower has his Individual Bullet with own Behaviour which can be Adjusted through the Tower Upgrades.

Implemented Basic Features:

Different Towers:

There now 3 Type of Towers, Projectile, Energetic and Explosion. Each Tower has its own Benefits and Individual Upgrades.

Different Structures:

Command Center and Lamp Post, to give you more Income and Visibility.

Individual Upgrades

Each Tower and Structure can be individual Upgraded.

The UI Changes based on the Selected Tower or Structure.


Spawn Manager , Field Randomizer and Enemies

Random Playfield

The Player can decide how the Playfield is Setup.

Spawn Portals

Choosing the Amount of Portals that Spawn Enemies. Each Portal Spawns a certain amount of increasing Enemies over Time.

Spawn Spots

The Player can Decide how many Base Building Spots he wants to Play with.


The Playfield can be various Times randomized until the Player like the Setup.

Enemies Behaviour

Video Showing the Enemies Travelling through a Portal in Base Sketch Defender

The Enemies are Travelling through Portals and Teleport from Location to Location.

As Closer the Enemies get to your Towers and Structures as more furious they will get. So shooting and killing them in Time is necessary to avoid Damage.

Conclusion about the 24 – 48 Hours of Base Sketch Defender

We have been implemented and created alot of additonal Stuff. The Prototype of the Game is almost done and Playable.

The next Steps is to make the Enemies Decide when to Shoot and which Target to Shoot. Premade Sounds need to be implemented to give the Game more Action.

If there is enough Time in the next 24 Hours, we want to implement the Research Center to give the Player more Variation to Upgrade his Structures and Influence the Game.

The Highscore System needs his Section to get Displayed in the Game aswell as on our Website Stusse Games

Itchio Link: Score Space Jam #11 Game Jam: Score Space Jam #11

Base Sketch Defender – 24 Hours

The First 24 Hours of the Game Jam Score Space has been over.

There are 48 Hours left on the Clock to finish a Game after the Theme, Teleportation and Upgrade with Highscore List.

Stusse Games decided to make a Tower Defense related Game for this Game Jam.

Choose your Tower, Aim and Shoot

Core Mechanics:

Buy and Upgrade Towers and Buildings

The Player can Buy Towers to Defend their Base against Incoming Enemies. With Research and Money the Player can Upgrade the Towers and Buildings

Action Tower Defense

The Player has to Aim and Shoot with his Tower on Enemies to kill them.


Different Towers with different Strengths. Splash Damage, Higher Range, and other Abilities will give the Game Variation to Upgrade and play Through.

Teleporting Enemies

Enemies come in Waves through Portals. They also use the Portals to Teleport on the Field.

There are Different Type of Enemies.

Strengths and Weakness

Enemies have their Weak Points, some Towers might be Stronger or less Effective against certain Type of Enemies then others.

Highscore System

The Game has a Global Highscore System which Tracks Score, Survival Time and more.

Start The Project : Base Sketch Defender

So our Core Mechanics were Decided. Now we had to Build the Game around that Ideas.


We start Out our Rough Prototype

Placing Turrets and Buildings

Controlling Turrets and Shooting.

Shooting Turrets

The Player can Buy and Place his Turrets on Predefined Spots.

Those Turrets have a Range and beeing Controlled by the Player.

The Portal

Enemies Travel through Portals and Teleport from Position to Position

As closer they come as more they will Shoot.


Enemies Open a Portal at Random Time. Once the Enemy opened a Portal he is Invulnerable until his Teleport to the new Position is Done.

The Basics are Done

So the Core Mechanics are now implemented. It was Time to give the Game some Menus

Main Scene User Interface to Start the Game and Navigate through the Menu as Highscore and Settings

The Main Menu gets a simple Design like all Stusse Sketch Games. For upcoming Highscore and Settings the Buttons were also already implemented.

The Game User Interface from Base Sketch Defender

To Count the Players Progress we extend to In-Game User Interface and added for the Highscore System a Highscore Manager that keep track of the Killed Enemies, Survival Time and Score.

Highscores and The Database

Our choice of Database is the Microsoft SQL Database. In Combination with the Entity Framework it is fast and easy to Handle. Our Server and Database has already a Pre Setup during other Projects.

Code from Server to Access Player Information with Entity Framework

Player can Choose a Name, to make a Unique Identification we grab the Motherboards ID Number and use it as Unique Key to Identify the Players.

Database Tables from the Microsoft SQL Database for Base Sketch Defender Highscore System

The Database Design is relative Simple and contains 2 Tables. The Game Information gets send by the Player to the Server and everything gets Calculated on Serverside.

Conclusion about Base Sketch Defender:

The Game is in a Good State so far. The Core Mechanics are working. Now its Time to improve the Visual Quality and implement some premade Audio.

The Amount of Towers and Enemies will be Increased aswell as the Buildings and give them some Effect.

Stay Tuned for more….

We are Releasing our Aircraft Sketch Shooter on Monday 11, 01 2021

Aircraft Sketch Shooter Improvements

The Original Aircraft Sketch Shooter Project wasnt meant to be Released. It was more a Project to Test and Try certain things in Game Design.

We had the Plan to release other Games, which looked more Promising. But after a long Time we decided to took Aircraft Sketch Shooter and its Unique Style to the next Level.

Read More about the Restart of Aircraft Sketch Shooter.

Power Box

In June 2018, Aircraft Sketch Shooter become a Power Up and Down System, which can be used in different Kind of Games since the Design it very Dynamic and also will be implemented in future Stusse Games lsuch as Aircraft Sketch Booster.

Creating a own Input System

One Year later in June 2019 we went back to our Training Project and we have created our Own Input System for Unity. This Input System can be used in any other type of Game we gonna Create in the Future. It might be not necessary anymore with the New Unity Input System, but the System works.

It was a Rough road until the Point to be able to finally can Setup the Steam Page. It took a long time to get all the Informations ready, especial the Tax Informations.

But once the Game Page was released, we know now theres no Way Back anymore. We gonna turn Aircraft Sketch Shooter in a well Designed Arcade Action Shooter.

Over the Time the Aircraft Sketch Shooter have become alot of additional Features.

Redesign The Weapon System
EMP Bomb Explosion and All Weapon Systems Activated, Special Shot, Rocket Shot, Laser

We Redesigned the Weapon System. The Old one was very Hard to Use since the Player had to Press Multiple Buttons to Activate Each Weapon.

The Player also had to Collect Ammo in order to Use those Weapons.

This was not Fast and it was more Frustrating then Fun. So we Changed it up to a System you have to Press Just Fire and Collect Weapon Power Ups to Boost your Weapons.

Its now much Simpler and also makes more Fun.

Different Graphic Styles

To give the Player more Variation we implemented different Shaders and used Post Processing from Unity to mix in some different Colors and a Bright and Dark Mode for the Game.

The Sounds and Music

Always in the Background were those Sounds and Audio Clips running, We cant descibe how often we changed the Sounds, until this moment. It took quite a while to find the correct Sounds for all the different Elements in the Game.

When we First Announced the Game on Steam

The Game Size Increased since that Announcement Day really rapidly.

In just 2 Months the Project Size almost doubled the Size of Programming Code.

We implemented a Retry System, Added additional Boss Behaviours, Challenges.

We added alot of Effects to the Game and Animations.

All around this we also started to Build up our Twitter Account, Setup our Website and doing the Basic Things all around that.

The heaviest Time consuming Task might was to Improve the Quality of all our Aircraft Sprites. We took them all and Increased the Visual Quality of each Single Aircraft and Helicopter.

We are still Testing and Adjusting the Game Stay Tuned…..

The History of Aircraft Sketch Shooter

The Restart

The Project Files of Aircraft Sketch Shooter first were Created in June 2018

The Founder of Stusse Games used this project to improve his Skills in Unity and Programming over the Years.

Through the time passing, priorities Changing and new Ideas coming up, the Game Aircraft Sketch Shooter covered with Dust, always was picked up from Time to TIme to test The Founders Improvements in Game Design to create a Good Game.

In January 2020 The Founder of Stusse Games was suffering now from learning almost 4 Years Programming and Game Design. Many Games have been created, but nothing that really was worth to share. So He decided to took a step back from everything. 

In May 2020 there was time for a Decision, Continue with Game Design or doing App Programming, Software Programming , Web Design and other Stuff based around Computers and Software. Now he was thinking about different things, what is the most advanced Game in the pocket, what has the best design pattern, which Game can be finished in a good Time?

The Answer was

Aircraft Sketch Shooter

Video Information:

In This Video the Boss of todays Airfield 4 was finished.

This Video is from July 2018, When the Game just was started.
We never Plan to Release the Game at this Time, it was just for Learning things and trying different things in Game Development.

It was now May 2020, The Project Files of Aircraft Sketch Shooter were Changed the last time on 30.06.2019 aswell as the last playable Build

This Build  is now Free to Play to Everyone on Itchio. 
Download and Play It Now!

So this was it, Stusse Games decided now, with the Unique Style of Aircraft Sketch Shooter, to make their first well polished Game.

Video Information:

Captured in May 2020 when Stusse Games decided to Relaunch the Aircraft Sketch Shooter Project.

We decided to use the Unique Style of Aircraft Sketch Shooter to build up our Brand and make simple and good Arcade Games.

There are 2 more Projects planned already with the same Graphic Style.
Aircraft Sketch Defense and Aircraft Sketch Booster
More Informations after the Release of Aircraft Sketch Shooter

So the Game was well Designed already and with the new Programming techniques and Systems that has been created over the Time, it was Time to take Aircraft Sketch Shooter to the next Level.

We decided what kind of futures we need to Add to make the Game really something that looks like a polished Game.

The Original Game was Designed only for 5 Levels. Also the Difficult Systems were weirdly Connected. There was Plenty of Stuff to Change and Create. But Lets first take a Look on the Project Difference from 30.06.2019 to Today

Project Infos From 06.2019:

Unity Version: 2018.3.7f1

The Project had 73 Scripts

Maintainability indexCyclomatic ComplexityInheritance depthClass CouplingLines of CodeLines of Executable Code

The Game has 5 Levels, 3 Difficult Options, Local Highscore, Non Working Keybinding System, Alot of Aircraft Sprites and Effects. You had 3 Aircrafts you could choose to Play with, The Powerup System were integrated, but the Weapon worked in a compelete Different way.

We Write down all the Features we had and what we wanted to Add.

Clearly More Levels, More Aircrafts, More More and More of Everything.

In Order to make the Game more attractive the Shooting and Weapon System needed to make more Fun.

The Current Quality of the Aircraft Sketches werent that Great, they all needed to be Reworked.

We wanted atlast 10 Levels, so we needed also more Specialized Boss Behaviours, Boss Enemies and Sprites.

Achievement System was on the List aswell as Online Highscore List to give the Players some sort of Challenge and Reason to play the Game beyond the regular Levels.

For this there must be some Sort of Endless Level, where People can Face an endless and always Changing Environment, which also Leaded us to Integrate Challenges aswell.

To make the Game more attractive we looked for a way to make the Game Look more Interesting and we came up with the Solution that every Player can Choose their own Graphic Style and a Bright and Dark Mode was implemented aswell with different Color Setups for the Game.

The Gameflow needed more Consistency and a solid Time to Complete.

Over the last Couple of Months when we picked up the Game again, we had made alot of Changes and implemented alot of new Stuff.

From Animations to Aircrafts, the Changes are Huge and we hope to bring you soon a well polished Game.

Project Infos From 05.01.2021:

Unity Version: 2020.1.7f1

The Project has now 116 Scripts

Maintainability indexCyclomatic ComplexityInheritance depthClass CouplingLines of CodeLines of Executable Code

This is the Change, the Lines of Code doubled, the Size of the Game doubled, Instead of 5 Levels there are now 12 + Challenges. Better Music, Better Visuals, Better Better Better…..
