it's buggy but- OH MY YOU CAN RUN ON WALLS... take advantage of the glitch before I fix it I finally figured out x collision and y collision. I EXPERIMENTED WITH SOMETHING.... (turning when going on slopes) it did make it like sonic 4 though :/ you can stand on a slope y collision does glitch sometimes ARROW KEYS TO MOVE AND Z TO JUMP UP ARROW AND SPACE TO PEELOUT
credit goes to Sega and hyper potions how it works is it has 6 sensors. one on the right, one on the left, one on the top, two in the corners and one on the bottom. they are all collision sensors
