God this game is stylish, really really impressive. I think the humanoid controls were tighter than the cat controls (bit disorienting to walk upwards using left or right), but that wasn't a problem once you get used to it. I impressed when I found on my second run that the carts vary! very good way of making use of your levels, and I'm impressed that it doesn't feel jarring.
TLDR: Nice work!
Edit: Oh I also have to comment on the awesome character art, I really liked those character portraits.
