Yeah, this is great. Sounds like a really fun Sega Genesis game. I like the tempo increases at the ends of the Portland tracks. And the super-compressed "go" sample throughout. The tracks are all upbeat and fun, but they still have their own identities. Nice ominous buildup on the final track, with the twist happy ending.
The only criticism I can come up with is that the snare can be a little overpowering, particularly on those punk beats on the last two levels, but even that kind of adds to the charm.
Fantastic work!
