The Room is a puzzle video game developed by Fireproof Games. The game was originally developed for the iOS platform and released in September 2012. The Android version debuted as part of a Humble Bundle in March 2013 and was subsequently released on Google Play.
This series (Room 1, 2, 3) is literally my favorite iPad app in the world. I could play these endlessly, and always buy the new release when I see it. Wish they could put out new versions faster!
