Javascript 3D FPS Under 4K

From A. Wooldridge.com:

3D TOMB II is a first person shooter in a fully textured environment done in less than 4k of JavaScript by Mathieu 'P01' HENRI, originally made way back in 2004. The game was released again in June 2007 with new adjustments and additions.

Use the arrow keys to explore the tomb, hold X or C to strafe and press space to shoot. An exit to the next floor is always placed on the other side of the maze. The HUD shows health, ammo count, current level and score from top to bottom.

Works perfectly well on both IE and Opera, but not so much on Firefox and Safari unfortunately.
