Personally I think Re:Mind did a lot of things right. It actually encouraged me to finally beat the Proud mode save I had left on my shelf since a year ago. The new abilities are really reminiscent of KH2 for me and having Oblivion and Oathkeeper again really feels great to use. I just really wish they had been in the base game.
As for the scenario itself, the new cutscenes left my head reeling. Nomura really likes his time travel shenanigans. As for the secret boss fight, I am nowhere near equipped to beat Yozora on Proud. But I am aware of the two (two? Really Nomura?) endings. It makes me question which ending is the real ending. A lot of people are speculating that Sora losing to Yozora is the real ending. But is it really? It left me more confused and in desperate need for answers!
