Really interesting concept! It starts out very simple but once you hit a few things the dragon becomes nearly uncontrollable - you could easily build some kind of "Rage" mechanic around this, where you have to complete the objective before you lose control completely.

This game was done for the TeenyTiny DragonRuby MiniGameJam 2020. It is my first game. I used all the art from flappy dragon. I requested permission to @mobypixel which actually told me that I didn't need to credit him. But I thought I do it anymays!

Finally, thanks to DragonRuby Team to give away free licenses. It was really fun and a nice experience.
