Press "I" to change maps. The first map you start one is not as buggy as the map after that. Arrow keys to move, and hold up on ceilings while moving to stay on ceilings for a bit. You can't move backwards a slide when you are on it, unless you jump. There's at least one troll death in the level using a bug in the collision code to troll you. The code is edited in this remix.
Thanks to MONXTER for the original project scrolling engine v2.
