As someone who loved flash flash revolution back in the day, I LOVE this game. Also I really like that your team was the 'excess musicians' from the discord. I think the difficulty is perfect, although I may be biased since I play a lot of rhythm games.
My favorite track was JackLuxon's track!
Also, as someone whose done some rhythm game-adjacent stuff in Unity, I'm really impressed at how well this plays. Unity doesn't make it super easy to sync stuff to a beat precisely, so I was really happy at how responsive it felt (I played the downloadable version).
Great work!
