With just under two months still to go before he takes over The Late Show from David Letterman, Stephen Colbert apparently doesn’t have much to do with his time. So, perhaps taking a cue from the current Humble Bundle, he decided to make a game.

Not to be outdone by other games with long titles, Colbert’s is called The Late Show With Stephen Colbert: Escape From the Man-Sized Cabinet. It’s a text-based adventure game where, as the title might possibly suggest, Colbert attempts to escape from a cabinet he gets locked inside of. It would ruin things to spoil any of the jokes or story beyond that, but suffice it to say it’s worth at least a few minutes of your time. You can play it right in your browser at The Late Show‘s website.

The game runs on the open-source Twine engine, which, as we’ve covered in the past, is an easy-to-use tool that lets almost anyone create a game. How much of a hand Colbert himself had in actually crafting the game is unclear, though he’s happy to take credit for it on Twitter.

Colbert’s iteration of The Late Show makes its debut on CBS on September 8.

Full disclosure: CBS is the parent company of GameSpot.
