This game does what it sets out to do: A simple game of Reversi, two difficulty options, and basic controls. The ability to undo moves indefinitely, a mute button, (And if you play this game for longer then 5-10 mins you'll likely be thankful for it.) A longer, or perhaps multiple music choices would give this an easy 5-stars, as it accomplishes everything it sets out to do, and advertises, the music being the only slight flaw.
