In the game you collect giant puzzle pieces, to getting them is the puzzle. I wondered into a room and there was a giant frame with some puzzle pieces, I found I was able to move these pieces, but what's the point? In another room there was a bunch of Goomba-like monsters and a seemingly impassable gap. What am I supposed to do?
Well the point of Braid is to think and experiment. You have a rewind time feature to make up for your mistakes, but this feature changes a bit depending on the world you in. I won't go into detail, but after thinking about what I had done to reach the simple puzzle pieces in the first tutorial room, I was able to figure out what was needed to reach the puzzle pieces. The answers are hidden, not obviously marked like most games. This is definitely a thinking mans game, but it contains plenty of platforming. Just remember that every puzzle has an answer, it might just take some time to figure it out.
Braid is a great addition to everyones Arcade Library. It's got a retro kinda feel, but after some time with it, it feels very modern. One of the few must have Arcade games. Enjoy!!
