Spelunky

I was recently introduced to a game called Spelunky. It is a rogue-like game, with retro graphics. It's quite a challenge, and is very addicting as well.  Travel into a game, venturing deeper while collecting treasures and equipment.  The game itself is very easy to learn, but with so many traps and enemies, expect to die very quickly when first learning the game.  Give it a try, and let me know what you think.
