Zen: coloring pages for kids

This is so fun and addicting Good job to the company

It's great for kids. However, when i tried to buy extra drawings, the purchase is rejected without any error code!!!

Many pictures to fill with color. You feels like painting with real brush. Very easy music makes you feel more focused on art. Some categories are paid extra. It would be five star review if orientation will be not locked. Sometimes it is easier to draw in other position on tablet.
