BUGS. I'm trying to get the player motion worked out.
I'm running into problems with displaying grid materials... I'll figure it out eventually...
Character Movement + Grid printing are working alright now.
WASD now controls the character. Player physics were added.
The physics are all right, but the collision checking needs some work. it seems to produce false positives when you try to walk into a wall from the right side of it going left into it.
Also the game crashes when the character goes outside the field of play (outside the 1920x1080 grid)
