Sos Sosowski's comedic Windows and Mac adventure game McPixel has launched for Steam, becoming the first title to be successfully published as part of the Steam Greenlight program.

McPixel features more than 100 single-screen, 20-second challenges in which players must prevent explosive disasters by using objects found in the surrounding area. This week also marks the release of McPixel's first free DLC expansion, with more releases (including user-created levels) to come in the future.

McPixel is priced at $4.99.
