Spelunky has been ported to HTML5, allowing it to be played in any web browser now.

Before it was a frustrating XBLA game, Spelunky was a frustrating freeware PC game. And now it's a quietly, addictively frustrating browser game. Using a new version of the Game Maker software in which Derek Yu coded the original game, developer Darius Kazemi ported Spelunky into HTML5, allowing us to link to a playable version right here.

Derek Yu, Spelunky's creator, made the game using the GameMaker tool, and now using the HTML5 compatible GameMaker Studio, developer Darius Kazemi has ported the original game for web browsers.

The port, which took Kazemi about three hours, is not perfect, most notably for its lack of sound due to an incompatibility with HTML5. current issues include a lack of dark levels, the removal of any (random) level that starts on the right side. But on the upside, it's Spelunky in your browser, for free.
