I'm one of the few poor souls who hasn't played Braid yet. I don't have an Xbox so my choices are PS3 or PC. The game came out on both platforms a little while after the xbox version, so I was wondering if the content on all three is the same.
Are there extra levels or anything in the PS3 or PC versions? Are the graphics different/higher resolution on PC? Any other notable differences?
Also, (this part of the question is more subjective) I don't have a game pad for the PC, so it'd be played on my keyboard. Does it play ok like this or is this enough of a reason to go with the PS3 version?
