The problem with such a framework is that the native part is completely blackboxed. I would never consider to adopt an hybrid framework that does not provide access to code because of the concern that some corner cases, which I cannot anticipate, could not be covered properly. I wrote a board game application in which I mix 2d graphics with native UI views. In the end I chose C++ for the business logic + 2d part ( with cocos2d-x) and Java or Objective-c for the GUI part. While It has been sometimes awkward ( especially on Android ) I feel to have done the right choice at the time I started. I have been able to reause a lot of code and the tools and languages I have chosen are fully supported. If I had to start again today I probably would consider Xamarin ( at the time it was too much expensive ) or something like RemObjects Silver.
