Thanks for the feedback!
The game is a bit hard, I had trouble winning stages myself. After some feedback from friends, I tried adding more tips and tutorial text so it is a bit easier to get into it.
Yea, the overuse mechanic is a bit too harsh and I was thinking about how to alleviate it, but in the end, I had no time to implement any solution. One way I wanted to do it is that when you overuse an ability another similar type ability replaces it, so you still have four abilities, even if they are not perfect for the stage.
