Quake Minus: Qquak

Via Indiegames: Jan Willem Nijman's super lo-fi Quake game, Qquak, amuses me. There's something about the idea of creating an FPS that is lower-res than Wolfenstein that seems brilliantly perverse. Demakes often don't follow the exact principles of the game they're based on, but in this case it's a fully-functional FPS, albeit in four colours. It's also pretty entertaining: fast, and with an online score system.
