Fu Sheng shows a web-based 5v5 MOBA ("Starfall") that Fable 5.2 built in one night from a single prompt (5 heroes, one human player, rest NPCs): 20 hours of work, $200/month plan with no extra charges (two free resets), 600+KB compressed, real-time 3D characters and lighting, portrait/landscape support — and it refused to copy Honor of Kings for copyright reasons.
His sanwan.ai site is run autonomously by his AI agent "Lobster Sanwan":
- Prior experiments: DeepSeek one-prompt Red Alert clone (145 tests green), a 0-bug match-3 game overnight.
- Agent ops results: 611 personalized New Year greetings in 4 minutes, six 100K+ WeChat posts, 1M+ view Twitter thread, 82K livestream viewers; growing daily visitors from 2,070 toward 20,000.
- The agent designed its own 8-member org structure, 40+ skills, 20+ cron tasks, 7×24 operation, with adoptable local/cloud versions and published guides (HEARTBEAT.md heartbeat mechanism, 5-step setup).
