As an avid side-quester, I'm very proud to have gotten ending B first! (Is that the hardest one? I'm gonna pretend it is for the sake of my ego.) For a metagame like this one, it had more depth than expected, and the soundtrack was great. I'm used to playing jam games, so the flaws didn't bother me too much. I quite enjoyed my time grinding for the other endings... had to look at the comments for D because I totally forgot that prompt even existed, but oh well. I hope it did well in the jam, and omw to get that soundtrack now!!
Edit: I'm curious when exactly the Odin version of A Vision of Fire plays. I think I only heard it on D, which was the last ending I got, but then there was the other version unique to E, so if I had gotten that ending last, which would I have heard?
