Good but one thing. – Colors by Number® – No.Draw® Review

I would have rated this app five stars but I don’t like how you can color over the squares that you already colored in. It’s really frustrating to have to go back and fix it.Can you please fix this? Thank you.?? Other then that the game is really good!!!???????
