Hi gardener,
If I understand correctly, after opening the door with the 3 crystal - Ivo went through and the door closes.
The walkthrough then continues:
Turn around and examine the exit. Ivo says that it is related to the crystals outside
Go forward and check the boat with skeleton.
Take the paddle-board from the skeleton. Check the iron bar. Ivo cannot pick it up.
Go left and look at the door at the end. Check the 2 holders planking the bowl. They should hold the crystals.
Search the bowl. Take sardines in oil tin and a stone disk.
Take round stones from the ground in front of the door with opening-gears on top.
Check the door with an opening on top. As Ivo, jump through the opening on top.
---- Hope that gets you through a bit.
