The puzzle aspect of the game is very interesting. I would say maybe slow down the character a bit more because I was able to clear 3 or4 levels without using the reverse shrinkification at all.

Yeah, I considered doing that, but I had to work during the final day of the jam (until the deadline) so I worried that lowering the speed would increase the difficulty of the game too much and I wouldn't have time to change the levels to make it work. I programmed this game JavaScript without a game engine so adjusting levels was a bit more tedious than usual. If I change it after the jam I'll probably implement that.
