W to move forward and S to move backwards. and Move mouse right or left to look and press M for map! You can click to shoot but it looks weird and doesn't do anything. (Still very glitchy: some walls appear in the 3D world but not on the map... I don't really know why so don't rely on the map.) This kinda sucks compared to some other like 'Griffpatch's 3D Laser Tag v0.6c'.
Used some scripts from 'Raycaster Test 3' by @Swampert11 after my scripts failed to display correctly... but I did change it a bit. NOTE: The sound may sound a bit odd.
