A Ruined Route

In the next section, you will see a crack on the ground. These cracks cave if you step on them twice. So you can only pass over them once since the second time you do, it kills you.

Before you go, take the Quartz from the over in the background. It is a little hard to see because of the similar color with the background but pots have a little glow on them to make them easier to spot. There is also a second Quartz to the right side (as you stand in the entrance of this section) sitting on a pillar.

Stand on the crack and you will see a shining pot on the right edge of the screen containing another piece of the Gilded Skull. Take it and head to the left. You will come across another gap. To the left is a lever sitting above. Head over and flip it. Heading back down will cause the cracked platform to crumble, showing you what happens if you happen upon one that will give in. Hitting the lever will cause the gray platform to move towards you. Allowing you to cross. Cross the gap and you will see another puzzle. There are two cracks in the way. Just do not cross the same cracks and you will be fine. Pulling the lever will cause the platform to go back and allow you to head to the next area.
