I love the game. very relaxing except after awhile it freezes and I have to force stop the game. it ruins my relaxation because I instantly get pissed. hopefully there is an update that fixes this issue. very annoying. 10/18/20- I think there should be a feature where after you are done coloring the picture the lines disappear. It would look better in my opinion. 11/15/21 - can we have a freehand color ability instead of tap to fill
