I like the "Paper Mario"-style sprite animations.
The way the music fades out as you get further away, and phases from left to right as you move in different directions is a really cool and innovative form of compass. Also neat that it never fades out completely, even as I drove past the edge of the map, lol.
I never did find out what "E" does, nor did I figure out what to do with the coins. Perhaps you ran out of time to implement a "store" section...
Also, your hilarious and creative interpretation of the jam theme of "combine" as "com-bine" rather than "com-bine" gave me a chuckle.
