So, gonna be honest here: I tried the game and it was just... meh. It's really just a KanColle-clone, but with guns instead. There are minor differences here and there, primarily in player agency for the mission segments, but overall it's basically the same in principle and gameplay-loop. And maybe I've been spoiled, but I had expected a voice-acted story segment, or at least one in the intro. Considering how the story is done even more simply than GBF and FGO, they really should have some voice acting in it. Lots of CGs, though, but that's kinda standard these days. And to its credits, it managed to nail the tone to its intro right... but since it lets up for the sake of the tutorials right after that, the momentum is lost. And the girls are just kind of... ehh. It's not bad, but I didn't feel anything distinctive from them, even Azur Lane did better in that regards IMO.
That's what I felt from it anyways. I might be wrong or you might have a different experience with it. And that's cool and all, but I just really wasn't impressed by it that I've already uninstalled it in just a day. I've held longer with Memoria Fréesé (granted, that's because I was hoping that the bug gets fixed).
