In this post, I will point out some techniques or difficulties I had to deal with:Scrolling: I used a personalized CCScrollView with Parralax effect. Scroll view had to be resizable (to create 3 distinct areas: left/middle/right). It had to use bounce or not, swipe effect (with decreased speed) or not (for camera mode). Gesture recognition was a problem with children's small and imprecise finger: they need to scroll and touch animals. So i had to deal with the speed of gesture and speed of scroll (if the scroll is near stopping, touching an animal is treated).
