Pipe Area

Use the bloom to clean the wall, and you will see the 5 shapes with empty shape inside each shape



In the room, you have 2 graphs



The idea is when they are combined, they should merge to become the same shape on the wall. The correct answer here is 42535
Line 1: the 4th shape of line 1 is a circle and a star. Combining them would form the shape on the wall (the bottom right shape on the wall)
Line 3: The X and the clover combine become the (bottom left) shape on the wall
and ect with other lines. Each lines has one spot that if you combine the two shapes you get a matching shape with the wall.


Picture found on the wall in the pipe room.
Simply find the arrow on the control pillar and rotate the handle to the correct rotation. White should be 10 o'clock if we see the arrow as 12, blue should be opposite, and red on 3 o'clock


This is the large circle room with buttons. Find the flashlight, activate it (with E, close with Q) and light up the poster on the wall.

A puzzle in the same room as the flashlight. The answer to the flashlight unlock the left lock, the right lock has a colour in order of green-blue-white-purple. The answer is taken on the wall from the previous room. I don't know the real math behind it, because the way I did it was simply look for the line with with same colour pattern and its the vertical line 4. It start with a green 4, blue 1, white 6 but blue 3, not purple, here to look to the left of white 6, and there's a purple 4, the colour sequence is now complete with number 4164.
