ZigClimb is a full roguelike game written in 1 kilobyte of source. It's moderately challenging but very winnable. Sneak your way through the later levels by clever positioning and let the monsters fight amongst themselves!
The ZigClimb source owes a lot of its structure and tricks to the excellent 1KBRL A Journey to Hell.
