What comes Next after APCSP

I want to add a course for the next level after AP Computer Science Principles. What course is next; or does Code.org offer the next level?

code.org does not offer any more advanced classes. There is AP Computer Science A and a number of organizations have a curriculum for that. There is a possibility of students taking a dual enrollment course at a local college.

What do others recommend?

I was thinking about making a hybrid class of one semester web design and the other game design. I would be interested in using the Code.org platform for both as introduction/practice before moving to more advanced items. We do have CS A here and IB CS. But there are not many other options. I have been told if I created a class like that, it might be pretty popular.
