I switched to Easy, where I didn't have to worry about rhythm timing, and really enjoyed playing through to the end.

Found it a little annoying that the abacus selection always started in the middle, when I would be selecting from top to bottom.
I have to think about Crypt of the necrodancer due to the beat somehow.
only thing: if the web version is a bit laggy the sounds has some scratching (but more of an issue with my laptop lol)
It's incredibly fun to play, the rhythm is absolutely fantastic, and the melody is still stuck in my head even though I closed the game tab already.
What's especially impressive is how perfectly everything comes together as one cohesive experience — the visuals, the music, the rhythm, and the gameplay mechanics. Everything just clicks!
This is one of those projects that makes me feel genuinely envious, in the best possible way.
Bravo!
