on levels that have dont touch the buildings, put dynamite on the side of the building that is farher away from the other building.
If you do a tweaked tailgrab (hitting and holding "A" and then hit "S" and hold) while doing a backflip, you rotate faster.
if you get stuck behind a car and cant jump it, stop, let it get ahead, and then go, and jump.
You can adjust your angle when you bounce off the ground, it may not look like much, but it helps in the long run.
did someone say, waste of time? thats me!
p.s. this game dose waste time
