I have 3 designed books that have 10-13 pages each that require simple interactions.
The interactions examples are clouds or people moving across screen, tossing ball, butterflies flying and etc.
The average interactions per book is 22. Each book also requires a separate game interaction. Book 1. Take picture and picture goes on character dressed as knight fighting bad guys. Book 2 coloring book and voice recorder. Book 3 record voice over selected music.
I prefer Corona and Kwiksher (kwik2) so that I can review work and convert to all platforms.
