I think this is the peak of the indie first person puzzle game genre, because it has what all of the other games in that style lack: fun puzzles that are easily forgettable. That last part is so key, because forgetting puzzles that is the thing that makes replaying them possible. I'm still a few years out from replaying Fez because I remember too much of it. I could probably play Obra Dinn again this halloween and have a great time.
