The ideaChildren love funny colorful mobile games; and as a little amusement during boredom or during long car journeys this can be quite a nice activity.
If only there wasn't the annoying advertisements all the time. And those intrusive in-app purchases, without which you hardly can progress in some games. In short: unfortunately most mobile games today are so unbearably designed for commerce that you don't want to expose your offspring to this bullshit anymore.
That's why I thought about developing a game for the kids myself. After all, how difficult can that be?😉
The result is the Eierschleuder slingshot game: you stretch a slingshot with your finger and let it go to catapult eggs onto little yellow buddies, whereby various obstacles in the levels have to be destroyed or avoided. Basically a bit like the well-known Angry Birds.
ScreenshotsA picture is worth a thousand words, so first some screenshots:
- Three worlds with different characteristics ("Hügelland" - hill country, "Wüste" - desert, "Weltraum" - space) and each with 17 different unlockable levels
- Additional randomly generated levels so the game never gets boring
- Projectiles with special properties:
- chicken egg
- rotten egg (causes a stinky gas cloud)
- magnet egg (attracts everything around it)
- bomb egg (explodes)
- quake egg (causes structures to shake and to collapse)
- ostrich egg (heavy and powerful)
- laser egg (shoots beams around)
- gravitation egg (causes a black hole in space)
- destroyer egg (fires an all-destroying beam)
- Various enemies to shoot at
- Destructible environment made of wood, glass, stone and metal elements
- Mighty power-ups, funny pirate cannons, violent explosions, wild sandstorms, aliens, dangerous lasers, ... in short: everything a good game needs ;-)
DevelopmentIf you want to develop a game, you need a development environment and if you want to get results quickly, it is best to use a tool that is already predestined for game development. That's how I finally ended up with Clickteam Fusion, which I know since 1994 😄 when it was still called Klick & Play, and which now also offers export options as an Android app.
Developing a game with Fusion is completely different than with "conventional" programming. Instead of typing lines of code, the program logic is simply linked by drag & drop - analogously, for example, "If the health of the enemy reaches 0, then destroy the enemy".
Also, you don't have to tinker with a motion engine yourself, but simply assign a motion concept to objects (is subject to gravity, bounces like a ball, follows a path, etc.).
Of course, this makes things a lot easier and enables a way of working in which you can gradually design and constantly improve your game concept.
In this way, this gradually formed from a proof-of-concept to a fully-fledged mobile game. Although I didn't work on it continuously, but over several months.
