Mooncake Shop is a time management game where your objective is to open a restaurant and serve your customers the best way possible. The app provides you with various challenges, gives you access to plenty of gameplay instructions, and automatically saves your progress.
You can play the game in fullscreen or windowed mode (you need to press the ESC key to enable windowed mode), disable sound effects and music if necessary, and access gameplay instructions whenever you like. The app also lets you replay missions if you're not happy with your final score.
On every level there's a number of customers you need to serve and your goal is to reach the goal listed on the upper left side of the screen. The faster you complete your orders, the higher your final score gets.
Nevertheless, I wasn't too impressed by this time management game. It brings low-quality graphics and levels which might seem annoying to some users (it's hard to keep up with the customers flow), it doesn't allow you to create multiple player profiles, etc.
With that being said, I don't think it's worth acquiring this game for your Mac, even with a price this low. You can find better strategy games to play on your spare time that don't bring you the aforementioned flaws.
