I respect what this game is trying to do with the multiple endings, but god damn, it does not make it any more fun to spend maybe a third of your overall playtime on repeated content with little change in gameplay. (This is speculative, I only got to Route B before deciding I wasn't built for this.)
I like everything else. Every character in the cast is great. Weiss in particular is my favorite but they all bounce super well off of each other, both for comedic and serious moments. I can tell that Yoko Taro is cooking some insane shit with the plot, good enough for me to at least want to watch the rest online (a rarity when I drop games, tbh)

EDIT: Okay, I watched the extra content online. I don't feel anything about this at all, and for something that's supposed to require so much time investment to get to, that's not acceptable to me. If I wanted to experience sadness from wasting a bunch of my time, I don't need to play a video game.
