From the developer:
Rooms: The Main Building... Discover a 1930s throwback upon your arrival to Rooms, complete with city streets and a surreal Mansion. Bored with old puzzles, you're given a new type of sliding puzzle as a birthday gift. Your goal is to reach the exit before it closes on each level and retrieve the four puzzle pieces. Are you wise enough to use the right object at exactly the right time?
