This is an interesting asymmetrical puzzle game for two players. One person plays Ren who is coma sleepy thus can't speak, and has to still give clues about what card colors they have hidden. The other player gets to play Feth, who also probably shouldn't talk, but has to chase away ravens through the art of puzzling up groups of 7's.
This game is harder than it seems at first, in part because the rules aren't the best, and you also get more rules as the story goes on, plus switching sides does really give you a unique game experience. We are six games in and still looking foreward to finishing off the story, however I'm about ready to give it a break and try something different, because I'm not a huge co-op game fan.
