Up / W / Tap top of screen to jump. Jump in midair to double jump. Down / S / Tap bottom of screen to fast fall. Jump on a rail to grind it. Jumping off of signs gives you an extra boost. Red rails make you go faster. Watch out for THE DEMONS....
Thanks to @miclack for making the original game, which is way more complicated than anything I could make on my own. There was no way to lose that game, though, so... I made THIS version. Player character speed is slightly modified, and there are 2 demons, but the rest of the game is identical to the original.
