Very good The software lives up to its promises.
If you want to use it while you're travelling Japan, it's a very good tool to communicate with people, because it has Chinese voice output and you can rotate the pic in the upper screen by pushing the L-button, so you don't have to turn your DS around when showing it to people. Very good idea.
The only letdown for people who want to train their Chinese is, that the game doesn't show the pinyin transcriptions.
Nonetheless, 5 stars for a great software. (It's not a game)
