I've replied to the viewer, and waiting for reply. but if the matter is look and feel, just let me know which one I copied. not just said:"same feature set as other apps " most of Chess game has "same feature set as other chess game". just look and feels different.

I think, if he/she want, that can do it by him/her self, I cannot help. but I can said, my APP can beat PC version good Chinese chess program. with same resources usage.

thanks, I submit to "Apple Developer" already.
