AI Tools Used
Treachery was built by one developer working with Claude Code. Claude wrote nearly all of the code, tests, documentation, art and audio. The art is drawn entirely in code, and the music is synthesized in the browser. I made the calls that needed taste. I set the game's vision and tone, corrected the rules, chose the art and UI direction, approved every haunt design, picked between the art options Claude offered, and decided balance by playing.

Each milestone followed the same loop. Claude wrote a plan with open questions, and I answered them. Claude kept the core design work for itself and handed well-defined pieces, such as new cards, UI components and test suites, to parallel sub-agents. Every change had to pass automated checks: unit and end-to-end tests and thousands of bot-vs-bot games that flag haunts that stall or are lopsided. A separate AI reviewer then audited each milestone. I triaged its findings and playtested the build on desktop and phone with a checklist, and my notes shaped the next plan. Later in the project the loop ran as a pipeline: Claude built the next haunt while I played the last one.
