The obvious way to describe it is to say that it’s Portal in 2D, but that doesn’t really do justice to what Gateways is. At its most stripped down, that’s what it is, certainly. You get a gateway gun and can use the triggers to place portals which can see you reach otherwise inaccessible platforms. Even some of the puzzles are familiar from Valve’s masterpiece, such as clearing long distances by generating momentum and then firing a portal onto a wall.

Smell that? That sharp, intoxicating aroma? Assuming you haven't forgotten to do the washing up, that's probably the smell of possibility. Microsoft's ID@Xbox program represents a serious and very overdue step up for self-publishing on Xbox - long consigned to the sporadically fecund depths of the Xbox Live Indie Games channel.

Most of the games available on it are poor clones of popular games, games filled with pictures of barely clothed cartoon women or farting games rife with quicktime events. Most people will stick with Xbox Live Arcade when attempting to find an independent game to play because otherwise their efforts will be akin to searching for a dime in a fountain full of pennies and cement."
