I would second the adjustment to the density, easy fix though! I liked seeing a racing game since there really weren't many at all this jam. Mechanically, the controls work pretty well. A few more arrows on the course would be helpful since it's not always 100% clear what's coming up given the camera zoom and that requires you to be decently timid with your speed. Died on a few tracks that way. Lastly, setting the player to the proper rotation on death when respawning at a checkpoint would go a long way to upping the gameplay feel. All in all though, not a bad little racer!
