Game starts with a fly-through the village. Dragon is assembling to your left and running to your position (far left-top left of village). Focus on the screen and hit the "c" key to change to First-Person camera. First suspended skull will be in front of you. Collect it, then find the other 11. If the Dragon breathes her icy breath on you, you die & begin fly-through again. WSAD to move (+Shift for speed). Collect all 12 skulls and she becomes immobile and her breath is harmless. You can then explore the village in peace.

Bug: WebGL version didn't maintain the Level-of-Detail for the Skulls. The play-through video on the page you came from will give you an idea of where the Skulls are
