Like others have mentioned, the art is stellar; lots of style and visual flair! I liked the different color palettes, too (the pink-on-black especially was gorgeous and fit the city theme well). Also the big head in the runback sequence caught me a little off-guard even though you warned me :)
There's also something very dark about the big head's voice lines when you realize that the protagonist isn't actually a rat but the sleeping character from the title screen. Made me uncomfortable, but in a good way; it's nice that there was some thought put into the broader story.
I liked that the levels were big and required some exploration; it also made me pay attention to the layout as I was working my way through because I knew that I was going to have to go back through eventually. I enjoyed working my way through both levels.
The main thing I would have preferred is, given that I'm on a skateboard, I really wanted a sense of momentum to the movement; this is one of the rare cases where I actually wanted less control over the movement, mostly to make it match with being on a skateboard (which wouldn't be able to stop/turn on a dime like this).
All-in-all, this was a really solid jam entry, and I had fun with it. Kudos to everyone involved :)
