Hey! hyper-neutrino here - I notice you've already clarified but yes, Vyxal is originally made by code-golf user Lyxal and not me; I've contributed minimally to it but I would definitely recommend checking it out as it's a great project and goes a lot more in-depth and is way more organized than what I've done :) hence why I've pinned it to my profile. I do have my own programming languages though; my best one so far is proton[^0] though it's pretty buggy because I wrote it in high school before I took the uni-level CS classes that taught things like language design and how to make actual parsers.

He's written a few of his own programming languages too: https://github.com/hyper-neutrino/proton
