Particle/Block RPG Engine - 0.25

I am working on a particle and block based RPG, and right now I am just developing the engine. This is a small look at the system. I would like feedback if you have any.

I made it so that when you attack, the player stops moving then resumes moving when your attack is done. The Maze - Slide file included is my attempt to make the block slide along the wall. It doesn't work. I think I am probably just missing a small thing somewhere. I am going to go through it later, but you can look at it if you like. (It uses the player.(direction)pause variables) The download is much smaller this time, only about 4.2 MB,
