Very clever way to integrate the Expansion theme. Pretty fun game overall. The level design could use some work. For instance I went gameover on a fly that flew into me very quickly, I simply couldn't inflate the balloon fast enough. The balloon physics could use some work. After deflating the balloon you don't start falling until moving right again.

Despite some quirks, a very solid jam entry. I love the name of your game, probably the best name in the whole jam. :) Keep up the good work!

Very Cool 👍
