Love the Art of course. I really like the Colour-Palette you chose.
I think the Gameplay is the weakest part of the it though. The avoiding of the Bullies is trivial and you generally only have to roll if three of them spawn to block all Rows at once. Maybe keeping the "Up-and-Down"-Movement not bound to fixed rows would help there (more of a Brawler-Type-Option).
But i know that it is really hard to have satisfying Gameplay in only 48 hours. The Look and Mood of the whole Thing is great though and i guess that is what you were going for afterall.
