Update: version 0.98.1 released.

Spelunky is the new procedurally-generated 2D platformer from Derek Yu, developer of several memorable freeware games and co-creator of the award-winning Aquaria. In it, players assume the role of a treasure hunter who ventures into the Colossal Cave in search of gold coins, gems, golden idols and damsels to rescue.

Areas are randomly generated whenever you start a new game, and the money you've acquired can be used to trade for items in shops. To proceed to the next level, simply search for an exit which is usually placed somewhere at the bottom of every map. You can carry dames towards the exit for an extra health bonus, while golden idols award more money than coins and gems although you would have to watch out for the boulder trap that awaits thieving archaelogists. By lending money to the tunnel man, shortcuts to levels five and nine can be built for quick access from the start menu. (Let's Play Spelunky)
