Move mouse (or arrow keys) to look around. W and S to move back and forth (or up and down). A and D to side step, space to jump. Press E to toggle map. When the map is open, A and D rotate view instead of sidestepping and the mouse will not rotate. FPS is the current frames per second. Higher FPS = smoother gameplay. FOV is the field of view. Lower FOV zooms in, higher FOV zooms out. RES is the resolution, the higher the RES the better everything will look, but will get more glitchy. There is no purpose to this it is not a game. Huge thanks to @griffpatch for his amazing tutorials!!!
