Gateways, Smudged Cat Games' entry into the Indie Games Summer Uprising, is on sale for 80 Microsoft Points ($1) on XBLIG, for a limited time. Smudged Cat is the developer behind The Adventures of Shuggy, and Gateways is a game we're thoroughly enjoying on Steam, where it is $5.

Gateways normally runs 240 MS points via XBLIG, so if you're intrigued by a retro 2D platformer with a series of matter-melting guns that just so happens to be a Dream Build Play 2012 winner, check it out now for cheap.
