I’m glad you enjoyed the demo!
Unfortunately, I’ve not so far planned any poly routes because I don’t think I can juggle writing that with everything else I’ll have to tackle lol. But never say never, and I like that there’s interest for the player w/ their spirits. I think that dynamic would be fun to write even if I can’t imagine Rei being happy with it haha
For getting that option, you’ll need to have brushed the snow from Caine’s head back at the festival c:
Also lemme take this chance to say how things are going rn:
A few days or a week ago (idr) I was intending to excitedly post that I figured out an ending I was satisfied with and was gonna go back to writing & coding the demo, while anticipating that sure, the ending might have to change when I actually got to writing that portion, but that could come later!
After I made myself slow down… I returned to a plot point I wrote that I need to revise. It’s messier than I thought but important enough I shouldn’t hand-wave it away for later 
TLDR; ASFJHEFHJBWEFK MAYBE IN OCTOBER I CAN ACTUALLY WRITE-WRITE
