With paid version you still have to sit through the long ads. What's the point. Tried using the chat feature with no answer or refund. Game is nice otherwise.

Tries your patience, but overall great game.

This is a fun little app. That said, there are some things that don't work for me. Some of the drawings seem carelessly drawn. Little specs that need coloring, and having to zoom in all the way to pigment them is a pain. There are a couple more things like trying to figure out where to poke w/o having areas changing colors of everything around it. But for free...
