it freezes every now and then when rent is being payed. It becomes unresponsive and won't even save, so the game is lost. Also, when in full screen mode, the Apple menu bar at top of screen won't disappear, so the game board is partially cut off. Also, the variety of cards in Chance and Community Chest is far less than the real game board. I'm not sure why they would limit it to such a small selection. Otherwise, the animation and movement of pieces is very nice, and the different skill levels is very useful. Nice job, but needs fine tuning!
