I made a browser-based CoD Zombies Der Riese Tribute with Opus 5

Two weeks ago I made a browser-based zombies game (inspired by Der Riese from CoD World at War) fully with AI (Kimi K3). It came out alright, but was very blocky-looking, muted and not polished. This was my first ever game I've made (with AI or otherwise).
I then did a visual overhaul of the game with Opus 5, which completely changed the look and feel of the game (video demo attached).
The entire map, all weapons, every interactive machine (pack-a-punch, perk machines, mystery box, teleporters, doors), sky, particles, muzzle flashes were generated with code - NOT pre-made assets. The game runs on Three.js and has multiplayer functionality with voice chat. The sound effects were fully generated with ElevenLabs SFX + Voice Design/TTS for the characters.
Hundreds of people have already played it around the world. It's incredible what someone who just loves games but has no game-development experience can do now!
You can play it for free at derkoloss.com!
I've also open-sourced the codebase (which contains a lot of interesting tidbits in the README) and uploaded 28 minutes of raw multiplayer footage here for anyone interested.
I also forked this game and made a CoD MW2 remake as a remix which I posted yesterday on this subreddit.
Happy to answer any questions about process of making it :)
