This game has been out far too long for there to be any excuse for its current state. When you attempt to play this game in 10.3, as soon as a level loads, all the sounds for that level begin playing simultaneously.It's completely disorienting and makes the game impossible to play. Macplay is aware of this issue and is apparently either unwilling or unable to do anything about it.
If you're running 10.2, you'll probably enjoy this game. If you have 10.3 or are planning to upgrade, stay away. It doesn't work.
Anxiously awaiting a patch but losing faith that there will ever be one.
