This is a portal gun test where I tryed to make the portal gun, and a test chamber to go with it from the game portal. I plan to make a whole game with my portal gun, with at least 20 chambers. Tell me what you think about this game and if you like the idea of a whole game. Also tell me if I should change/add somthing. the song is Still Alive from the real game. sonic is wearing a yellow cape.
