Neat concept, but the game definitely could have used some polish. I had a hard time finding the three "downgrades," the sound effect clip got annoying pretty quickly, and eventually I got a Javascript "memory out of bounds error." Also, the signs were too small to read, and the "good guys" moved so slowly that I could just run past everyone.
Still, there's only so much that can be done in 48 hours, so good job!
