Kuli, That's really my point. I scoured the rift five or six times before I returned to that area and my cursor happened upon that area of the pillar that causes the cave in.Plus, there's that gigantic room next to the lava that you might think has something to do with advancing, and it is completely useless.
Plus, there's a door that tells you a specific item is needed, when really you can't get anything to open it at this stage.
Plus, how many people tried to cross the lava more than once to see why they can't get over a stupid rock at the end of the tunnel. Frustrating.
I'm not saying I want the game to be easy, just a little more logical in places.
Don't even get me started on the Rune puzzles...
