Very cute art, the game idea is also very cool!!! I noticed some things that could make the game feel better, like when you squish eggs into walls they are very likely to go through the wall into infinity, I think you can try to handle this by setting the continuous collision detection on the eggs rigid body. Also small think I noticed is that you can sort of double jump if you tap jump too fast, I think this is because of the way you implemented coyote time, if you're using time buffers you can set it to 0 right after you jump the first time.
Anyway very good entry, I wish to see more games from you guys!
