I thought this was super fun. The core gameplay is actually a really fun sort of puzzle-platformer without any jumping. One of the more unique gameplay concepts I've seen in this jam.
The level progression was also very smooth. You taught concepts and tricks through the levels naturally, and built up to some pretty tricky levels that felt satisfying to overcome.
It took me a while to realize that I was dying from hunger (I thought it was a bug at first), so maybe some sound effects would have been nice there.
Great stuff here :)
