While it's clear you ran out of time, this game actually has some good stuff cooking already!  The sleek logo is nice, good loading screen, a creative idea for gameplay.  The systems aren't explained because I suspect they aren't fully implemented, however you started in the right spot.  Hitting perfect notes has great audio and visual feedback.  The monster and character sprites are cool and the main character running up to start the fight is nice.  You should definitely keep working on this I'd like to see a completed demo of the concept! 

While yea it’s unfinished this game is conceptually really cool LOL Never seen a music creating game, just like, in general before, I think you could take this rly far. The idea of a roguelight where you build up a full unique song to play through sounds sick The one thing I’d say is to maybe change the way notes are handled like they are in traditional rhythm games where it plays at a set time and doesn’t play if you miss, because even when hitting perfects the note would be slightly off beat when it wasnt a PERFECT perfect, which felt slightly punishing but at the same time it IS satisfying to actually play on beat lol

Great game!

Super cool concept. The beats feel punchy and it's very satisfying to hit the right "marks".

Maybe some tutorial part/instruction could be helpful in the beginning.
