main(){puts("Hello, World!");}
This is using GNU C extensions. GNU C allows main() over int main(), ss well as using puts without including stdio.h.

Basically just keeps replacing the current cell value with the ASCII value of whatever character in "Hello, World!" its printing and moving on. I might add a more detailed explanation later (or maybe someone else can, if they feel like it).

Hello, World!
I'm surprised no one even used Charcoal in the challenge. Guess I'll take it.
