I literally made an account because I need to gush about this game in a paragraph.
The gameplay is visceral and intense, while also being simple, making it easy to get the hang of, while also extremely satisfying. I've been playing it all day. It does an amazing job of making it feel like you're really clashing swords. The sound is great, the graphics are pleasant, the arenas are cool, and the gameplay makes me squee. Of course it could use some polishing here and there, but I'm still completely satisfied with how it is released now.
Mr. Developer Sir, I really hope you continue to develop this game; it'd make my lifetime. This really is the ultimate fighting game for me. Despite being so simple, it gives me the same rush as Sekiro.
