Virtually unplayable on Mac. I spent about 3 hours banging my head against the wall trying to get features in this game to work, an hour of which was spent hunting down and reading the manual online. The game is very, very laggy. Sometimes the game will respond correctly to a mouse click, other times it's like you never clicked. Very, very confusing to figure out what is going on in the game as the game is very unhelpful and the port is buggy. Ultimately, after reading the manual, I realized the game was just extremely buggy and there was nothing I wasn't understanding. Seems like it would be fun if it worked better.
