Love this app! But recently started freezing – 3d Voxel Art: Color by Number Review

Im really in love with this app! Everything about it is perfect! This past week though, the app has started to freeze where i cant do anything! It even makes my phone tweak out a little bit! Only reason I could thinknit started doing this is because I have almost completed all of the pictures. Please fix☺️
