Solid concept! Collecting new bone structures to turn into other animals was a neat idea, though there wasn't much use for the cat form once you get the mouse form as far as I could tell. It would have been fun to have to switch between forms.
Some of those early jumps in the vertical area below the clock were nearly impossible - seemed like I had to use coyote time to pull off some of those long horizontal jumps. Detection for warps didn't always seem to work - sometimes I would press E and nothing would happen. Wasn't always sure where I was supposed to go and there were lots of leaps of faith because I couldn't see where I would land.
I enjoyed the narration and the art was very cute with a kinda watercolory unfinished look that was appealing. And the end screen art was beautiful! Nice work everyone!
