First time playing it so I didn't know the possible moves, but they all came to me naturally based on map layout (except the last one, couldn't figure that out on my own). Good level design for teaching how to play.
This gap in rocks looks like an access to a secret area. 
Sometimes camera is really choppy. I think it might be happening when it colliders with the terrain? I don't think it's visible in the video because it's 30fps.
Why are small bones made out of weird neon energy, and big bones are normal?
Brown slabs textures in the building, next to mouse, look weird. Like they're too big compared to other things and lack detail. And windows look like they're supposed to form an arch, but they're squares.
Character model, textures, sfx and animations are super good. Very cute.
