Being able to fuse and save whenever you want as well as certain other mechanics make the gameplay feel super patronizing, cheap, and easy to break. The plot, the music, the world-building, and everything else are all great, but I think gameplay is a kinda a barrier to those in this case. This is a world full of Demons, Yakuza, Cultism, Terrorism, and all sorts of chaos, yet thanks to the gameplay, I always felt completely safe. It clashes.
