I've just been browsing through the episode guide, and just everything about this project, from the full-on tour-de-force vids, to Iker's weekly illustrations and the episode breakdowns. Reflecting on what i've seen so far (upto Day 21), I think this is one of the most amazing resources for game developers that exists and has ever existed. Thank you Casey for making this effort, I absolutely love your passion, and attention to detail. Even my girlfriend has spoken over my shoulder on occasion to praise Handmade Hero. It's just a phenomenal project.
HH has really attacked my fear of C/C++. Although I still find C debugging, error messages (edit: and method names, and so many other things) completely bonkers. I can at least write some C code now to call DirectX if I want to.
Thanks for all your effort. This is a most valuable project for game developers.
