I had a lot of fun playing this. The only thing that I would change is that when you die, you should respawn at the starting point (but keep the reset button). I spend WAAAAY too much time putting people in their stationary places after a failed jump, which was more tedious than challenging.
It helps to continually restart the map until the glitch doesn't appear...
It is annoying, though. I still don't know what half of the stuff in the game was because my car just finished the level without me!
