As everyone has said, the art is super cute. I can tell you two put a lot of thought into the character animation. And wow, that planet in the background looks amazing!
I found it difficult to parse the foreground elements with the background. Maybe consider lowering or raising the background's brightness to contrast more? I was also in desperate need of a restart button for when I got stuck in the pits!
It's too bad you didn't have time for the main mechanic. I hope you guys can get it to work!
