Level 12 (yet another)
OK, I'm stuck. I've set off the eye beam things on 3 of the pyramids except one. It's the one from the pyramid with that one block blocking the entrance into a room with an open broken door and a door I can't open.
Also I don't know what to do with the red beam; I can't step on it and I don't know what the hell you're supposed to do in that room with the little waterfall. I've tried the bucket in every possible position (I think), I've tried to pull that lever, but still nothing happens. Someone please help!
