VERY good game... The music is beautiful, easy to control yet VERY challenging puzzles, and it teaches you to think outside the box. It takes a classic game concept and flips it on its head.
okay for certain people 11 and up but never for everyone.
I would think Braid is appropriate for anyone 11 or 12 and up, but it's not for everyone. If you're the kind of person who can wrap his brain around some very tough puzzles, then this is your game. I would also argue that it is very educational. It can help train one's brain for logical and spacial thinking at a very high level. (warning. The difficulty curve is Steeeeeeep!)
