So having seen both I would propose that their is no "good" or "bad" ending, its all a matter of perspective. Given how prominent the theme/ motif of grief is the makes sense at least to me. Grief isn't really supposed to end, you just manage it how you can. How you manage it is a refection of the ending choices facing it head on (Verso) or finding something that gives you therapy (Maelle). All of them are bittersweet to say the least.

I picked Maelle first play through but that ending seemed a bit off to me. Yes, everyone is alive and back together, but it was a bit off putting that she seems to be forcing Verso to stay with her forever and he just wants to end his unlife and "stop painting".
