Greenhouse have posted up the PC demo of Jonathan Blow's time-fiddling, award-winning platformer, Braid. It's 120mb and contains a sizeable chunk of the game, with an option to unlock the full thing in exchange for $15. And, well, it's pretty damn good. (It even automagically detects 360 controllers being plugged in mid-game.) Thanks to Aaron for the tip. We'll be talking at greater length about Braid next week.
