This really kinda embodies what I'd loved about the original coolmathgames.com games. Looking forward to seeing more!

Updating my review: The second song you added is fantastic! And I'm really enjoying the live indicators of score and how well notes were hit so that is a plus, and the new ui for groups and stuff makes it feel so much more well-rounded. My only comments now is that with double notes, it might feel better to have the indicator on both notes when you hit it perfect/good or whatever else, or have it float out to the side or something instead of right inside the note spot. I also noticed that missing a note didnt break my streak in the top right, but I wont complain about getting more points for no reason lol

With some polish, this will 100% fill a gap on this platform. The music probably doesnt completely match the atmosphere, and i wish there was more to do in the way of obstacles, similarly to games like "The Impossible Game". Also wish the cube felts a little heavier/less floaty. I really like what you have for now though, keep at it!
