2d mario cart with no one against yourself! I love the idea for a lot of reasons. You are incentivized to drop the obstacles away from the fastest route because you want them to be out of the way, but to drop them there you have to waste time to go there in the first place. The controls are tight and I love that changing the car's size can make it easier or harder to hit obstacles.

Some music would really help it out (there is lots of CC music online) and the lap counter isn't working. Additionally, a smaller track (maybe with other levels) might increase the hectic-ness of the run and allow you to finish quickly.
