Voxelor
(I had a problem with the game after I finished the picture of the rabbit, so I had to reload Voxelor. The colors became numbers, and that is about the only way to restart a picture on this app. I just tried out the idea of paying only $3.00 for a month!)
Did they make a change in Voxelor where they now tell you how many of a numbered cube remains to color (such as 40 of the number 5)?
I like that change!
