I only played for about 2 hours, but I can already tell I'm enjoying this game a lot. The background and environment looks so damn beautiful, this is definitely a work of art. The controls are simple, a variety of attacks with just the control stick and A button, you can make up some crazy-ass combos to kill everything, it's so much fun. Each katana has a unique special attack (B button). The Quick Draw attack is a full screen attack, it's extremely useful for those swarm encounters. Momohime is pretty damn cute, don't know much about Kisuke yet. I wish I had found this game sooner, I be missing out, dood. I don't think I'll ever go back to my Hayato in MapleStory. I definitely recommend Muramasa: The Demon Blade.
In other news, some more minor amiibo hunting. Found Wii Fit Trainer and Mipha (finally got all Champions).
