Great game! for the PC and I\\\\\\\'m selling for £12. The outline of the game is that you are this little spacey feller and you have a gun that creates portals. It is a puzzle game and the difficulty of each level increases at ever game. You have to use the portals that the character can create to your advantage. It\\\\\\\'s great for people that enjoy a challenge. I have tried and tried and still have not managed to complete this game! (my patience has not vanished, I\\\\\\\'m on another one). Emails for Jeff, ask what you need to know. Its in great condition :)
