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.

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 music when turned ON.
Music state is context-aware:
- Title/start screen uses title music profile.
- Gameplay switches profile by biome (Plains, Desert, Jungle, Snow, and Lava mapped to the Volcano profile).
- Death screen switches to death music profile.
- Restart/respawn to start screen returns to title profile.
Turning music OFF performs a short fade to mute; turning back ON fades in the current state profile.
