A 'prime' idea for a game. It's awesome. I would love to see a version with bigger screen sizes and updated graphics.
(Please excuse my derivative pun - I'm doing them in math this year)
This game is awesome, although the second is better. decembersun, it is totally different then Mario. The physics and wall-running/jumping is way cooler then Mario.
After exiting the tailslide with the up key release up and then press it down really quickly and hold it. Then you get some good tailslide speed. Also, starslides add to your tailsliding effectiveness.
