Love the cute art style! I wasn't sure how to play the game at first so I went and actually looked up how to play Chu Chu Rocket. Once I got that down, the game actually seems pretty fun! Of course, I didn't have anyone to play with at the time, but I'd imagine it'd get pretty crazy.
The only complaint I have is that there's no tutorial. I could also see this game getting more content in the form of obstacles and whatnot, but this was fine for a jam game. Anyway, good work on the game! Keep it up!
