Very nice, and impressive in 13k! I played a race or two against a friend, I love to see local multiplayer games in jams =). Controls felt good, except one point where our cars got stuck on top of each other for about a minute :D. I wish there was slightly more gameplay, maybe just a refilling boost meter, or speeds high enough that you need to brake around corners or something. The cars, track, smoke all looked wonderful, I like the style!
