I cannot climb up the blocks in the z shaped room (where you come out of the water tunnel in search of the green gem), they are too high. I can find no other way, and the walkthroughs just say climb em. Please help me, it's driving me nuts. I just can't do it.

Hi, You have to jump and grab the lowest block, climb on it and walk through a (door)gate towards the tracks you've been before, turn right and jump/grab the next block, than walk back into the Z-shaped room. You are than seen from the pool in the upper right corner. If you don't see any gate to walk through (I encountered that problem in someone else's game), please mail me, I have a saved game for you.
