This game is the best puzzle game I've ever played, it messes with your mind in ways you wouldn't believe, the mechanics that the creator(s) have come up with are crazy, and i have only discovered 2 of them, I am going to keep playing and see the rest. The description doesn't lie either, every level is handmade, and unique. The mechanics and levels get harder and more mind blowing with each one. If you like puzzle games and the concept of infinity you'll love this game for sure. Worth every penny.
