Really simple game but it could get more interesting when you'll add other minigames.
I had some trouble understang what were the effectsof the three powers, so maybe more straightforward icons (maybe with a little name under them) could be useful. Moveover since you don't usually use the arrow keys it took me a while to understand how the "GET" minigame worked: I just forgot I could move.
Anyway this could be a really nice project when it will get more content. Good job!
