Use the arrow keys to move and turn, and use the a and d keys to strafe left and right. The FOV warps the maze depending on where you put it. It's just like Minecraft's FOV since everything appears smaller so you can see more when it's turned up. The RES changes the detail or the maze. The lower it goes, the more detail there is. The higher this is, the less lag you will have, but the less detail you will have also.
I didn't make all 5 parts of the tutorial because not everyone will want enemies, so they don't have to take them out if they don't want them. Also because I'm lazy and they take forever to do.
