9 Opus 5.5 Agents Cooked Survival Stats Into Our Game

I wrote one page of rules. Claude Opus 5.5 turned it into a team: one orchestrator and nine AI agents. One night (and one morning) later, our survival game had health, energy, thirst and hunger, all wrapped around a compass. They wrote the code. I didn't write a single line. In this devlog you'll see the whole build: the spec, the plan with contracts, the rules that let AI agents work side by side without breaking each other's code, the reviewers who found over 40 issues before I even opened the demo, the usage limit that hit at 11 PM, and the final survival stats running in Godot. Plus what it all cost: $214 at API prices. ⏱ CHAPTERS 0:00 9 AI agents, one night 0:35 Our game so far 0:52 The rules: survival stats 2:09 Health, damage and a bear 2:52 Sleep, waking up and refills 3:53 The orchestrator's plan 5:04 Team rules for AI agents 5:41 Nine agents at work 6:27 The reviewers: 40+ issues 7:38 Usage limit at 11 PM 8:00 The compass decision 8:40 The result in the game 9:19 What it cost 9:55 What's next 📊 IN NUMBERS • 1 orchestrator + 9 agents (Claude Code, Claude Opus 5.5) • About 3 h 45 min wall-clock, about 8.5 h of agent work in parallel • 15 commits, 13,000+ lines, 1,097 automatic checks, all green • $213.91 at API prices (on the Max plan it's usage limits, not a bill) ABOUT THE SERIES From Code to Game follows two brothers building a survival game for Steam with AI as part of the team. It's set in the Beskids of southern Poland: exploration, survival, and some very weird things in the woods. We build it piece by piece, mistakes included. Subscribe to follow the whole journey.
