Excited for the upcoming release of the Xbox 360 version, I played the original freeware game. It taps into a really specific Rick Dangerous nerve in me that makes me enjoy Spelunky more that I ought to. :)
Inspired by 'Spelunky 2' being released soon, I'm warming up by playing the original GameMaker game. It's very similar to the remake, but the subtle differences are very fun. For one, I have a pistol in this one.
