In Number Sequence, the child is asked to draw a picture by following the numbered dots in a sequential order. The issue is that some of the dots are hidden behind the navigation buttons for GCompris. Those buttons can be hidden, yet I would imagine most kids would not know that right away. It could be confusing and/or frustrating for users, kids and parents alike that do not know about hiding the navigation buttons. Nothing serious, just a thought. Also, the resolution for the pictures gets very stretched and skewed when rotating an Android device. It does not break anything, that I am aware of, just looks very odd.
