Wow, a really cool combo of a rhythm game and action! Although a tutorial would help - it took me quite a while to figure out what at all is going on :) But after I figured - wow, great game!
Although, while a big fan of rhythm games, I found it a bit too hard when the rhythm changes. Timing your move is already hard when you tap the rhythm with your other hand, but when it changes - it becomes a bit overwhelming. I'd suggest the same rhythm - maybe as an option for "easy" difficulty or something.
That said - fantastic game, very unique and captivating. And kudos for Godot!
