The game is mostly fine. Negatives: 1) lots of ads that end my audio feed. I like to listen to music or audiobooks while playing and the ads cut off the sound and do not restart the sound later. 2) The game seems to think it's hide and seek rather than coloring. Random small pieces seem to be hidden, which is annoying. 3) I do not like the "rare" designation that adds extra colors. Positive: I like the detailed pictures.
