Zero Rock Entertainment has announced that Rooms: The Main Building, now available for Wii and DS, will arrive via Steam on July 11th. This is a game where you'll have to use extraordinary items and devices to navigate through a variety of rooms and buildings. In each room, players must use intellect, strategy and various objects to solve each puzzle. To make it into next room, players must carefully shift pieces in the current room around, in a manner similar to slide puzzles, to keep moving forward. Players are also rewarded with a bonus if the background is placed correctly. With more than 100 rooms to go through and a level editor to create even more, players will discover that the solution is only a doorstep away.
