Now you've geon and dun it!

Anyone with a fondness for roguelikes and 10 spare minutes should check out the excellent freeware PC game, Desktop Dungeons.

Made by indie developer QCF Designs, Desktop Dungeons is a re-imagining of the traditionally complex and lengthy roguelike game as a quick, single screen RPG/puzzle hybrid that at first glance appears to be a simple, accessible little time waster but is in fact a surprisingly deep and replayable game.

Just like any Roguelike, it features multiple classes, monsters, items and randomly generated dungeons but each playthrough generally won't last more than 10 minutes. Most initial attempts at conquering a dungeon will result in your horrible death at the hands of the all-powerful 'boss' monster, but as you keep trying again and again the ingenious subtleties of the combat and levelling system begin to make sense. Once mastered, you'll find yourself unleashing hell on your foes instead of just being their supper.

QCF Designs have really hit on a winning formula here, but as great as it is on PC this type of experience really belongs on a handheld console. DS Dungeons, anyone?
