This is a very fun timemangement game with some differences. I'm using yosemite and have had no trouble with the game in terms of bugs or being unable to proceed. All works fine. The game itself is simple but not too repetitive as there's different things to do rather than just buying items for travel agency and sorting customers. You take customers on flights to different destinations and play various minigames whilst there. The only complaint I would have is that there's only 3 travel agencies to play, which makes the game rather short..it would have been nice if after getting all 24 service awards (achievements) for the other 3 agencies (8 each) it unlocked a bonus travel agency or something along those lines. Apart from that would recommend highly for anyone wanting something fun and easy to pass the time.
