Fireproof Games' The Room [$0.99 (HD) / Free] is an amazing game, and dare I say it, one of the best atmospheric puzzle experiences you can even have on your iPad. Not counting the epilogue puzzles (Which I still need to set aside time to finish!) the game will take you a few hours to play through, at which point I can promise you too will be singing the praises of The Room.
If you need a refresher, take a look at our review of the original. The Room 2 is easily fighting for the top of my most anticipated games list, and December 12th can't possibly come soon enough.
