MovePlayerToVector works now. Added canMoveLeft/Right, for the walls. Doesn't work right now..
Removed the unused fallingSpeed vector, added a vertical wall to the level, added some logic for the canMoveLeft/Right thing, but it doesn't work right now with walls that touch the floor. Works with floating walls, though (if you jump against them). Slowed down falling (still have to change it to be more realistic?), made jumping consecutive (don't have to press up all the time, you can hold it now). Pressing K will teleport the player back to the spawn point.
