The downside of this game is I literally just has a match with a player that keeps making his moves even though the time bar has completely ran out, that's completely crazy and unfair! I'm pretty sure he keeps making moves for 10s even when time has ran out while i could never have make any additional move once the time is up. Guess the developers have some codes to pick who will win in a match. Other than that, this game is pretty fun and you also get rewards for completed albums.
