2x0ng:
2x0ng is a procedural puzzle-combat roguelike game rendered in an 8-bit retro style. Pronounce it "TOO-zong". You control a little pixel-person running through a procedurally-generated maze; with your bouncing, color-changing Squareball, you can match colors to unlock new areas, and destroy an onslaught of enemies as you make your way to the exit. The rest of the rules are for you to discover in-game.
