I used Opus 5.5 to build a site where you can talk to brundlefly: my half human, half fly mascot

I used Claude Code to build a home for Brundlefly's half-human, half-fly mascot. Wet walls, eggs, and a creature you can talk to. Opus 5.5 did such a good job; I initially was trying to with Codex but didn't get the results I wanted. Opus 5.5 was able to mostly one-shot any direction I wanted to take with it and did surprisingly well animating, especially given the "3d model" is really just a 2d image with depth.
