The author shared part of the prompt.
I made a 3D survival game in one prompt with Opus 5.5 Survive 60 seconds. Every tile you step on cracks... then it falls. Race your own ghost, chase near-misses, watch the arena rebuild itself when you fail. Most people don't make it past 30s 👇 https://claude.ai/artifact/D3kjdvMpvrGgTCcxDTTDvP
Games0:30This is Dope!
Claude Opus 5.5 is on fire 🔥
One prompt → a 30s video-game walk through Mumbai, built entirely in code.
No AI video. No 3D assets. No stock audio.
1,850 lines. 900 frames. 30+ sounds from pure math.
Every pigeon, puddle and kaali-peeli, made by code.
Mumbai, compiled. 🇮🇳
Games0:30I turned this into a full game with unity cli + opus 5.5, also opus did this full demo video, it played the game with multiple characters and spliced together the best bits, holy shit we're in the AGI era. Play it on your browser here: https://rehan-remade.github.io/hollow-crown/
