Use Cursor keys or W and S to move around, A and D to strafe. Use this for anything you want to if you're too lazy to make one yourself. Just go inside, shouldn't take long, you can change the color of the map, floor and ceiling (They're separate), and even more! Also, griffpatch has a tutorial on youtube to making your own 3D Raycaster.
