I generally find Mahjong to be too difficult, but I managed to get further than usual in this. It seems to have everything you would want in a game based on Mahjong. The only thing I didn't understand was how some of the game was played. It was weird to see different levels. It's hard to use depth perception with a game like this. Good thing I have two eyes.
The music was pretty good and I liked the Oriental theme. That obviously fits all the Chinese letters being introduced. Maybe they were some other language like Japanese? Anyway, it's hard to ask for improvement because any Mahjong fan should enjoy this. It just takes too long for me.
