I'm probably fairly near the end, but I'm not sure. I've been stuck in the mines for the past few days, totally confused about where to go next--or rather, how to get to the sandstone caverns, because I haven't found them yet. I know I have to find my way to some room while I can still hear the cart rolling around, but I've wandered and wandered and can't seem to find the right place to go. :( I'm guessing that until I get to the sandstone caverns, I can't make a proper diversion in the landing dock either, but I'm not sure.

So, any hints on how to catch up to the runaway cart?
