I made my AI agents build a pixel art game by hand

I gave two models, GLM-5.3-Flash and DeepSeek V4.1-Flash, the job of building pixel animations and then turning them into a game. Every piece of art is a matrix of hex colours rather than a generated image, so each pixel is placed one at a time. That hand-placed approach kept the results surprisingly clean. If you want the earlier attempt at hand-built AI art, watch this video.
