I've just gone back to Egypt with the intention of trying to finish this particular adventure. I'm supposed to be getting the Relic of Life from the Tomb of the Desert Ocean, and I have merrily been working my way through the Pyramid of the Sky. According to Carl's Egypt guide, you're supposed to explore the area on the right-hand side to get the keystone for the left side. My problem is that I can't find this flipping keystone!
I haven't got Pangu's axe, so I can't get through the boulders. I also used a star keystone to unlock that unnecessary door in the first right-hand room, so now I can't unlock the door into the little side room on the ground level. If the missing keystone is in one of those rooms, then I'm stuck. I've looked all over for hidden doors, but I think I've explored everywhere that I can explore! Unless you're meant to do something with that mummified bear....
Help?
