This game is the perfection of Portal. Everything good about Portal was improved on and everything bad was eliminated. The single-player is good. The co-op is interesting. And the level designer is amazing. The ability to create and play your own puzzles and the puzzles of thousands of others means this game will stay alive and new until people stop caring about it. And everytime you solve a puzzle, you feel that much smarter.

There just isn't another game like this one. If anything about it looks interesting (and you can handle the system requirements) you should get this game. It is difficult to describe Miasmata in a way that makes sense because if you judged the game based on its description, the game wouldn't be that impressive. It's as unique as Braid and Portal were in their time though in a completely different way. I can only hope they make more.
