Man-eating plants! Skeletons! Giant spiders! Falling boulders! What do these things have in common? They're all very, very deadly. And they, along with a host of other unpleasantness hungry for your demise, are waiting for you in Spelunky, an incredibly addictive roguelike platformer from Derek Yu.

With randomly generated treasure and dungeons, steel daddy-long-legs, giant eggs and killer babies, you're in for a long trip.

Puzzle Dungeon is a funny little roguelike adventure game written in javaScript. You start off with your stalwart adventurer on the surface, and descend into a randomly-generated dungeon of ever-increasing complexity. Solve simple puzzles to open chests and mine for gems. It's a fun little diversion, a game that you can sit and play for a few minutes of hack-and-slash action and then let be.

Nethack is a classic singl-player (randomly generated) dungeon exploration game that runs on a wide variety of platforms, and yet each implementation uses the same game engine. But whether graphics or text-based, emphasis is on discovering dungeon detail rather than just killing everything in sight.
