I can see this being useful in the mental health space for children and young adults. Mindful-colouring is often used as a tool to help young people suffering from depression/anxiety/psychosis/ trauma keep their troubled mind quiet. While physical colouring-in does help, it can be tricky to keep them engaged as there is no purpose or real use for it once the picture is completed.

This could help to solve that issue. I can picture psych wards with virtual fish tanks/jungles etc to help keep patients engaged and entertained.

Probably not the original intention for the game but just an observation I thought I'd share.

I've been holding AB1 for what seems like an age now and have averaged down a couple of times. I remain confident that it's a keeper though some days that red is hard to take!
