Oh shot, is that a sentient Fumo?
I really like the idea of a battle happening on the beat of a song! Though I think the songs themselves were quite awful, no offense. I just can't word it another way. It's a rhythm game so I had high expectations for the music.
The in-battle dialogue mechanic is really interesting but I see it wasn't explored, probably time constraint?
Also I am quite weak in DDR-type games, just trying to mentally match the notes with what key input I should do is hard enough for me, so the horizontal chart scrolling against my fingers' disposition not matching the display makes it even harder. Though I think that's on me.
I am genuinely interested in a refined version of the game.
I featured this game in my Jam showcase video:

(Also does the illustration where Youmu and Reisen passionately kiss show up above a certain score? I can't tell for sure)
