So it's an interesting idea, but the reaction time needed to win seems a bit steep. When I turned some of the buttons on/off it took a few tries for the action to work (for example I had to spam on/off for shrink to work). If you're going to have the player need to react quick you need to make sure the animations are also smooth (or you feel cheated since you thought you pressed the button but it didn't work!). I'd clean it up and you'd have a fun little game!
