Play the game Notch made in 48 hours

This weekend's iteration of the occasional Ludum Dare game-making marathon, in which entrants have 48 hours to create a game from scratch, had a celebrity participant: Minecraft creator Markus "Notch" Persson, who spent the weekend developing a first-person dungeon crawler called Prelude of the Chambered.

If you'd like to see what happens when Notch rushes (in contrast to the still unfinished Minecraft) you can play the game in a browser window. Like, right now. Here's the link. "It takes about 20-30 minutes to beat the game," said Notch, suggesting you might be able to get back to work today. Of course, he immediately followed with "if you die, you need to start over from the beginning," throwing your workday back into question.
