Use the forward arrow key/w key to move forward, backward arrow key/s key to move backward, left arrow key to look left, right arrow key to look right, a arrow key to strafe left, and d arrow key to strafe right. Also, to pull up the map, hold m, if you let go, it will go away again. And, to change RES, click and hold r, and yet again, if you let go of the r key it will go away.
I used Griffpatch's 3d tutorials to make this. Also, I used a song from "The Rolling Giant" (by Cane Pixels).
