Nicole_Chen just dont make your opinion about game now(as of 83.0 spring engine), since it is quite broken now because of new release of spring engine(83.0) in 82.7 all works nicely. New releases of engine always are more or less buggy. I wish you good luck.
And you look at yourself very critically you offer free help and you think devs wont accept it if it is not perfect? wrong. Even it would sound like chinese from mars it is still better than no translation who dont understand english at all, you can always write something like this "dont like this translation?, make it better" I have submited my voice in childsplay with similar writing, because I wanted my sister to learn to count and read alphabet faster :) She has old P2 laptop with all sorta of educational soft runing linux since age of 3 or something :D
I dont know how big percentage can speak english in china, but at least in Lithuania all young people can understand it more or less at least enough for be able to normally play games, so there is no big point in something like Lithuanian translation unless you want some childs appearing here :) Personally I always prefer english version than localised one.
