This game is a lot of fun! The idea is really creative, and fits the theme perfectly. The difficulty curve does seem to be a bit off though. Level 2 and 3 took me five minutes to beat, while 1 and 4 took only maybe one or two. Another thing is that when you shrink, you can jump again in the air which I assume is not intentional. Besides that, I think you made one of the best games in the jam!
