If I could offer some constructive criticism, I feel like this game took notes for its in-song ui from parappa the rapper when it should have been taking notes from um jammer lammy, it feels like it's hard to know exactly when it's my turn to press buttons. Also I feel like sometimes having my buttons get pressed on the same line as the rival, and sometimes be on the lower line is weird looking, why not just have it be on the same line every time? I don't want to sound too harsh, I think the demo is good and maybe I'm a scrub or something but making it more clear to the player exactly what they're supposed to do and when is key to making a rhythm game work
