I don't think that this game was needed. People who are saying that it is just as good as Portal have never played Portal. However, I have to give this game merit for clever coding and all of that. The level designs aren't exactly inspired, but the portal gun mechanics work fine. I would rather just play Portal, but I guess I can see the value in making this.
this is the game which makes me want to punch my computer.
This is game is so cool :D
I love this game awesome use of physics and portal mechanics, been playing it for years whenever I'm bored and have a computer at my disposal
