Thanks for playing, glad you enjoyed!
There's about an 8-frame window to get a PERFECT and like a 15~ one on top of that for a GOOD iirc, specifically because I know some of the boxes are a bit off-beat. It's pretty tough to manually set accurate beats, at least when it's my first time making a rhythm game. As for Yakuza 0, it's mentioned in the second sentence of the itch description lmao.
