Please,even though I'm using MaGtRo's walkthrough,I don't know how to step on the slabs in order to open the gate.Do they both have to stand on the slab at the same time?Can some one tell me exactly how to step on the slabs? I'm talking about the anomalies animals on the slabs.

See if the instructions here help.

Sometimes looking at more than one walkthrough can be useful.

Let us know if you are still having trouble with it.

Thank you very much,what a great help!

You are most welcome. Enjoy the game.
