@ryo Just viewing the source of his site, he even has WASM on there.
BTW, It seems like you are looking for C game development tutorials, judging from Dylan's Youtube/Odysee channel. Parallel Realities has SDL tutorials written entirely in C.
@ryo The site that I linked has SDL tutorials entirely in C. Parallel Realities is a FOSS game development team that writes their games entirely in C.
@ryo You should also check out Masahiro Sakurai's (creator of Kirby and Super Smash Bros) YouTube channel. He focuses more on game designed rather than game programming (mostly because getting technical could reveal trade secrets), but his videos are pretty interesting.
