Bamzooki

I loved Bamzooki as a child. It was a CBBC show where you designed creatures and made them compete. Note, I doubt anyone had ever made a Zook that acutally could walk back then, I remember trying for weeks and barely got past the newborn giraffe phase... Nobody has made anything like it since and with my previous game experiments working I tried to get Opus 5.5 to build me one. I didn't write the code. I wrote this paragraph, typos included. Build me Bamzooki (look it up) but with better graphics and easier to navigate. It had such a fun idea to custom make a robot that moves proper physics challenges etc. Create it with Three,js, use wavespeed CLI for any graphics, audio, background music, sound effects etc. that you might need, (also can use it for images and such with GPT 2.5 Sunburst or Flare etc). Feel free to add any tutorials challenges modes or w.e as needed, multiplayer with friends to show-off or challenge each other, whatever you think is best. Choose your own appropriate stack for this as needed. Whether you use Godot, pure JS, Vite, React idk. Your choice to make a great game like this. Feel free to fan out to sub-agents as needed, ensure you're tracking your development of this given your prallelism with workflows and sub-agents to ensure proper adherence to your architecture, steps milestones etc. Ensure you critically review gameplay and whatnot with adversarial reviewers who acutally load up and play the game, review proper game theory, playability, looks, UI, visual, sound etc. Also do any relelvant resaerch on game theory, bamzooki itself, or how to make things like this, physics etc. After that I sent about a dozen short notes over two days. Most were design picks (ive got a claude md addition that any frontend design needs to go through me with 3 variations minimum to pick the best applicable style. I only got ot this phase once hte majority was built. Opus 5.5 did the rest in one Claude Code session. It used about 50 subagents and ran three rounds of playtests where agents loaded the game and played it. The stack is Vite, TypeScript, React, Three.js and Rapier physics. The walking is never animated. When you press Teach, an evolutionary trainer tries about a hundred rhythms in a web worker and keeps whichever one gets furthest. The physics is deterministic, so a friend's run can be re-simulated to check it. The daily board re-runs every entry on the server before it counts. Agents that actually play the game find bugs that tests miss. The odd leg flailing at the start of a run turned out to be the test pad starting before the zook had landed (even a millimetre out of whack at the beginning sent the leg stumbling). It never asked me to describe a design. It rendered a few real screens side by side and I picked one. It took 46 hours, including a night's sleep. The bill at API list price came to $1,045. Overall though, im just shocked it works, ive kept coming back to it to play more, its like a childhood dream come true.
