Gameplay Rules

• TRex starts with 5 hearts (or 10 hearts in VIP mode).
• Easy and Medium end with a portal that advances to the next difficulty while preserving score.
• Moving forward earns score (+1 per forward step unit).
• Water gaps cause instant death if landed in.
• Ant collision costs 1 heart; jumping on ants crushes them.
• Pterodactyls unlock after score > 100 (duck to avoid).
• Meteors unlock after score > 250.
• On death: top-10 leaderboard is shown; top-10 runs can be saved.

Leaderboard persistence

• Backend endpoint: api/scores.php
• Data file: data/scores.json

Audio / music toggle behavior

• Music defaults to OFF when no preference exists in localStorage.
• Toggle preference key: dinoLand.musicEnabled ('1' on, '0' off).
• First user click on the music toggle resumes/unlocks Web Audio and starts procedural background music when turned ON.
• Turning music OFF performs a short fade to mute.
