I've been wanting to play Monument Valley for some time, but haven't, mostly due to my old phone having close to no space (now I don't have to worry about that). Though I've read in the reviews that it's "really short" and thus "not worth the price" but I also don't know what is too short for some people. For me, it would be under an hour, but even then, a couple of bucks doesn't seem like a waste of money for something like that. I'm also pro-games-that-I-can-finish-in-a-couple-of-sessions-because-I'm-an-adult-and-don't-have-time-to-binge-a-100+-hour-game.
