Since you liked cantata so much, I think you would seriously enjoy God Cursed, it's pretty different in a lot of ways, but is also an incredibly good story!
I played God-Cursed before Cantata and absolutely loved them both. I can't wait for Lunan and Fir to release their next updates (I understand it is difficult to work quickly as I am trying to make my own IF so I don't want them to rush). Zahn was my main RO choice in GC, followed closely by Rune, so you can probably guess that Calliope is my favorite followed by Corinne. What can I say? I like adorable girlies with that hint of trauma (at least in these games, as I have gone after men or other archetypes in other genres).
