Description: A bit untidy in places, but the yellow key room went well. The zip includes a more entertainining but slightly slower demo: a 2:16 with plenty of low health and a nice finish. :)

The obvious route is to pick up all three keys and then to make for the exit, but I found my path was always blocked by a big swarm of monsters then. That's the reason why I press the red and blue switches before going for the yellow key - it draws the monsters away from the exit area.
