I don't touch LLMs, they're bad for you. I made my game with Krita, Blender 2.79, Trenchbroom, EricW's Tools, GCC/MinGW, Vim, and a lot of late nights fueled by sour gummies and energy drinks.
No gen-AI. I made these with Photoshop, Ultimate Doom Builder, Slade, and a lot of caffeine & paracetamol.
