If I've played just enough of the ingenious Gateways to know one thing; if I play much more my brain will end being the shape of a pretzel. It's the game that John raved about while describing time travel conundrums so defiantly opposed to the natural flow of reality that even reading about them made me feel less like a professor of puzzles and more like a hobo of the brainsphere. A cerebum, if you will. As of today, the game is available to buy at the official website for $9.99 (there's also a demo). I'm going to step back in because it's the first puzzle game since SpaceChem that I've felt justifies the mind-knots that I'll spend the morning after unpicking.
