30 days with Opus 5.5, 227 commits and Blender MCP turned into an actual game headed for Steam. I Just Wanted to Fish is being built in Unity, but the interesting part is the 3D workflow. Most of what you see was created by Opus 5.5 through Blender MCP, including the animations. The workflow goes pretty deep: > Opus 5.5 + Blender MCP for most 3D models > Blender MCP for all animations > Unity for the game > `CLAUDE.md` to maintain a consistent art style > consistent visual references for asset generation > usually 3–4 iterations before an asset is right Opus 5.5 even wrote a custom tool for creating difficult hand poses in Unity, which are then used for animations like holding a fishing rod or making a fist. The audio is one of the few parts that isn't AI-generated. It's recorded manually or sourced from free libraries. All of this after just 30 days and 227 commits. This is getting way beyond “AI made me a prototype.”
