So I'll split this into two parts: Story Telling and Mechanical.
Story Telling: From a story perspective, none of the other characters really did anything outside of direct confrontations with Brie. Prior to vamps he didn't seem to have done anything. Emiya assisted a bit with vampires but ultimately Brie was the one to actually do something about Caster. He tried to track down Olga and failed, found Assassin only to fight Hans, and didn't even get Hans to use a command seal. The info gathered from Assassin was useless, since we already found out Olga was with Kiara. He sacrificed Saber to take out the monster Olga summoned but considering his earlier failures helped lead to this it's kind of a wash. Finally he brings in mother fucking King Arthur as back-up as he sort of helped Medb stall lancer for three minutes!....whos contribution was ultimately cut some branches as Medb kills Lancer herself? It really only felt like that served as a way to tell players "Hey if you tried to not save the town you'd also have to fight Last second seiba on top of Ruler." Speaking of Ruler, whaaaaaaat was she even there for? She handed out a couple command seals and helped stall Cu as once again, Brie went to actually solve the problem. Outside of that she "Couldn't help" because reasons, even though things got so bad the Clocktower were nuking the town. Speaking of, both the Church and the Clocktower only really exist as faceless entities that are driving the "Time limit" plot. Neither managed to note that Kiara has a bounded field up over the town pavilion or whatever, despite supposedly trying to find the supplier of the magic drugs. Outside of Olga ganking Kiara, Archer trying to snipe Brie, Caster unleashing vamps, and Cu targeting Ruler no one did anything but Brie. Worse, of those incidents only Caster's vampires occurred because of incidents that weren't involving Brie. Nobody served as anything aside from antagonists for Brie to fight. Caster had her vampires which Brie beat down, Kiara was doing something with drugs that Olga took over because Brie beat down Olga, Brie beat down Olga again, Emiya watched, Minerva ran, and Hans...stood there I guess? Despite having his own forces and being Shishou's student he didn't really do anything besides fight us and repair Brie. Also the lack of any foreshadowing regarding Minerva's intant-win button that explicitly led down the Heaven's Fell route felt very
Diabolus ex Machina.
Mechanically, I mentioned it before with the fight votes and such but most options didn't really give any indication of what they did. Social votes obviously indicated who we might talk to, but it was ambiguous whether those would lead to increasing a social link, or a plot hook, and if we didn't discover the plot hook if it waited or got worse. Combat votes were especially nightmare-ish because it always felt like we were getting by by the skin of our teeth. Using a gun seemed to be as effective as using magecraft or gae bolg, because whichever way we only seemed to dodge death by a hairsbreadth each time, and just felt like randomly picking, or blind votes. And if it's a blind vote, you might as well flip a coin because the questers have no meaningful impact on the choice. These compounded into the issue that was the Minerva fight, which were back-to-back "Pick gun, spear, magecraft, or pandora's box". None of them seemed to have better results than the others and then the final choice ended up being the choice for our route...but that was only mentioned on the page *after* the update. Even worse, Spear wasn't the "Heaven's Feel" choice because picking it caused Minerva to beat us, or killing Minerva triggered the route, it was the "Heaven's Feel" choice because it just happened to be the one that
got us in touching range of Minerva.That definitely felt the wombo combo of "Pick a random box" combined with "Also fuck you, the boss has a one-hit KO ability that was never hinted at".
Then later on we had the vote for Brie picking either her wish, or saving the town. Putting aside the inherent problems with characters that have done almost nothing to save the town putting all of it on Brie, or how it's the cherry on top of the "Literally only Brie can do anything plot-relevant", Brie choosing her wish narrowly wins. Then, rather than a run-off vote for a contested option(which I don't care what Spectral says, that is
not something I see anywhere besides Anonkun which has a very different questing structure) it's a vote for what
Medb thinks about the wish. Putting aside that up until now, Medb was her own NPC with no input from others, this felt like a run-off vote for "Are you sure Brie wants to sacrifice the town?" except
nobody wins in this case; the voters that want Brie to win for her wish lose because Medb won't let her, and the people who want Brie to save the town lose because Brie doesn't want to. You created a situation where
nobody wins, and
everybody is salty.
Finally, after that, we get a vote to pick a different protagonist. So now the quest ends...following a character that we may have spent the quest
with, but not
as.
The last two problems there might've arisen partly because of voters voting for them, but they were inherently problematic from the beginning. On top of that, considering that some of those voters were(and in fact, even now still
are) saying "How they want a tragedy" it feels difficult to see the winning options in any positive way with people seemingly coming in at the end of the quest to purposefully tank it.
Again, I love the characters and the way you write Rabbit, but please maybe keep some of this stuff in mind for the next quest?
