This is amazing! I can't believe this is a jam game considering the amount of polish. The artwork is really amazing, everything moves when you touch it and the music and writing are great. At one point I'm not sure how I died but still, this is amazing. I had no idea that 2D artwork could work this well in a 3D environment.
One minor complaint I have is on the character controller: it feels a bit stiff because there's a short delay from when you push a button and when it starts moving, and a slightly longer delay when it should stop. Also while the side animation puts his feet quite in sync with the ground, the front and back look a bit like he's skating.
Anyway, great game guys, congratulations!
