The idea is fun, and it fits the jam very well.
It's also got a lot going for it. I think it's designed about as well as a jam game can get. The levels (that I managed to get to) were all good, and the challenged certainly ramped up.
I only got as far as the level where you have to push one of the cones to the end of the track with the turns; the one right after the coin collection level. I was just getting nowhere lol.
I had fun, and the execution was great. I'm not sure I would like to play this as a full-length game though lol. Maybe as a minigame within a larger game, perhaps a larger driving game.
