I LOOOOVED "The Room", but it's too short

You can probably spend about 5 or 6 hours and finish it. But you CAN'T put it down (if you like puzzle games... if not, then you won't like it).
I liked "The Conduit" on the Wii, I suppose the same should apply to the Android version. Of course everyone is playing Candy Crush Saga right now, so I guess it's addictive (I've refused to hop into that wagon). Where's My Water and all their spin-offs are quite good, too... and they keep adding level after level. And although it's getting old, Angry Birds and its derivatives are good, too...
