Is all of your work done today? Are you sure? OK, if there's nothing you need to accomplish over the next few hours, click here. You're now playing Spelunky in your browser, and your productivity is dead.

The port was created by Tiny Subversions' Darius Kazemi. He notes that Spelunky's in-progress HTML5 edition was made possible by GameMaker HTML5, which allows the compiling of GameMaker games in Javascript. In its current state, the port lacks sound, and required multiple hacks and fixes for stability's sake.

Regardless, Spelunky is still as fun as ever, and this new version makes it that much easier to resume your addiction at any time.
