Indie platformer Sideway: New York, which made its debut on PlayStation Network as part of Sony's "Only on PSN" promo, is no longer a PlayStation exclusive. The game has made the jump over to PC, and can be found on Steam right now for $9.99.

For the uninitiated, Sideway tells teh story of Nox, "a street-smart graffiti artist" who gets trapped in the walls of New York City. You'll have to jump and spray your way out to survive.

The "PC-optimized version" is being developed by Fuel Entertainment, and promises multiplayer co-op and support for keyboards and game pads. It doesn't appear any PC-exclusive content will be included with the release.

To coincide with the launch of the game, headphone manufacturer Skullcandy will launch the "Get Your Tag in the Game" contest, which allows "aspiring street artists" to create artwork for the game. You'll be able to enter via the company's Facebook page.
