"PlayStation 3 might happen in the future. What's going to definitely happen this year is a PC release. The only reason that's not out right now is that I wanted to focus on one platform at a time," said creator Blow, last year in August. Well it's been almost a year since then...
Braid is a "limited exclusive" after all, so the USK is likely right. See the clip below for some gameplay footage - you know you want to, go on.
