Brilliant level, my dear sir. It would be even more awesome if you extended the race so that it goes upward. For example, the springs that end the race could pop the player up to a higher level of the volcano. From there, you could race around, and pop to a higher level. The top of the volcano is the end of the race!
Heh. Just an idea. I understand it must be very difficult to make a level like this, anyway. Good job.
