# /runner-tune — Difficulty & theme ## Goal Adjust **numbers and theme** on an existing `games.js` / `index.html`. Do not replace the Spawner/hook architecture unless the user asks. ## Examples ```text /runner-tune wing --gravity -32 --flap 10 /runner-tune moto --speed-max 50 --accent #33e6ff /runner-tune loop --jump 15 ``` ## Process 1. Read current `CONFIG` and `:root` CSS variables. 2. L1 short plan of keys to change. 3. Patch only those keys; keep comments. 4. Suggest playtest checklist (mobile touch, keyboard, mute). ## Do not - Rewrite mesh builders “for fun” - Change `mode: 'side'|'forward'` without explicit request - Invent external leaderboard endpoints ## References - @../../rules/runner-conventions.md - @../../rules/approval-gate.md
