Thanks, Andrew!

I'm very intersted in Qt UI, and I don't want XAML as GUI for my game. We
choosen Qt Quick because Qt Quick :). We have experient with cocos2d-x but
we changed to Qt because Qt is fully cross-platform, stable, cute code
model and special QML. But C# calling is mandatory in my company, because
many our modules and frameworks was implemented in C# or must call C# API,
then we very interested in CX.

And, we use AdMob for banner
