This is sort of the reverse of Skyrim: instead of killing dragons and collecting dragon bones for some reason - you collect dragon bones to build a dragon.

You have 10 seconds (obviously) to find all the poorly textured dragon bones. Drawing dragon bones is hard. I've never seen one in the flesh and suspect they might not exist.

The potions look enchanting but they are just for decoration. Consider them vials of orange juice.

Update: Fixed in Firefox where the canvas was offset weirdly (Chrome seems very accepting with width="120.px" bogus values). Also music can be paused.
