Very nice. It was actually an interesting experience to notice how my brain slowly rewired to understand how the coordinate system is remapped to finish platforming challenges. I've especially noticed it during the vines tunnel level - once I understood it could be simplified to just playing on polar coordinates it was pretty easy, but before that I struggled to avoid the fireballs.
I also got inspired by 3Blue1Brown video and made a little prototype, but never got past that stage. Nice to see someone not only created a game, but also a visual treat for an eye and brain!
