Hi!
Thank you so much for your comment!
I think self-care in game design for me is = empathy? It's difficult to define it, but I think that when you are making game design about self-care for other people is all about you trying to think how the people can feel with this and that.
Game development as meditation is more like an exercise for healing in your inside. It's, basically, another way of taking outside your inner worries.
Thanks so much for the link to the Carewave Manifesto!!!!!
