ok this took me like 20-30 minutes and i got stuck here too but i finally just realised what you do and basically you just push the two sunken logs up and then push them horizontally and then walk onto one of the sunken logs then you push the vertical facing log onto the rocks and then put in into the black water then you walk up and yeah
when the door is open go inside take the box put it on the one that opens the door, then go on the one that opens the other door that goes down, bring the box with you, put it on the one that opens the later door, open the first door with yourself, shoot a bullet, wait till it goes past the door, then pause and go on it then unpause and jump to the next level
