/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

/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
