Very quirky but functional platformer engine demo, followed by a seizure-enducing racing game. The platformer engine seems to work by locking the player's NS movement and then applying reaaaaaaallllly slow gravity. The player will also have a hard time going up 1x1 slopes and jumping off of moving platforms because of this. I'd recommend just programming a simple physics engine for a platformer, with velocities and downward acceleration, instead of trying to salvage this for your own game.
