Another Dawn (UP)

MISSABLE, When exploring the cavern (Level 2) you'll come to a long straight away with the option to keep heading straight or take a left turn under a rock and you want to keep heading straight and you'll come to a room with a small spiral mountain go to the top of the mountain and the Achievement will unlock.

For those who prefer video guides I show this achievement in my walkthrough at 10:31 minutes into the video.
