It could've gone for a creepier ending in my opinion, the moving stone head at the end left so much answered about what they were doing there and their purpose. But all in all, beautiful point-and-click, best one I've played in a while.
At first on the third level I saw the quake but never heard any noise so I ask myself what the heck am I climbing on, beat the level; HOLY CRAP GIANT FLYING SEAHORSE.
