===========
Puzzle 1
===========
Hint 1:
The drawing in the right drawer has one big white square. Look around and see if you spot one.

Hint 2:
Those Os have holes. What else do in the room?

Hint 3:
The drawing of the eight white squares correspond to the 8 walls in the room.

>>>> Solution:
The grid is the room's layout! The three middle squares in the middle row are the floors and the non-corner surrounding squares are the walls. Place Os on the walls that have a hole (3 windows and the white wall). Here is what the solution looks like:

_ _ _ O _
O _ _ _ O
_ _ O _ _

===========
Puzzle 2
===========
Hint 1:
Have you touched the die?

Hint 2:
The red wall has an interesting shape.... have you seen the shape anywhere in the room?

Hint 3:
The grey square to the left of the red wall corresponds to the grey floor.

Hint 4:
The target objects are the big yellow carpet on the floor, the red wall, and the blue chandelier (in the first room). Also, roll the die on the wall, not the grey floor.

>>>> Solution:
Imagine rolling the die around the room.

Now, read the die's face that touches the matching color.
* The original position of the die is already on the yellow floor, and the bottom face is 5.
(We didn't see 5 on screen, but it's the only unseen face. Also, you can use the fact that the opposite sides of a die add up to 7.)
* If you roll the die to the position below the chandelier, the top face is 2.
* If you roll the die next to the red wall (over the grey floor), the face touching the wall is 3.

Therefore, the solution is 523.

Puzzle 3
===========

Hint 1:
You don't need to open the glass doors. And you don't need to count anything.

Hint 2:
1 dot means it goes to the first position of the lock, 2 dots means the second, and so on.

Hint 3:
The dots clue the objects you see through the glass! The first one you should solve is the one on the right (grid).

Right:
The grid looks familiar, doesn't it? It is rotated 90 degrees, and the positions of the Os seem to be different. Can you combine them somehow? And can you read any number out of it?

Up:
Chandelier, huh? Yes, there are 6 of them, but we don't count here.

Down:
There is nothing... or is it? (Vsauce intro starts playing) Of course it's the floor! Why does the floor need to be grey? just like the one below the die? What else do you *see*?

Left:
There are 3 paintings. What do *they* see?


>>>> Solution:
All four sub-puzzles use the floor plan of all three rooms combined. The floor plan (viewed from above) is 8, where the final door is on the top. (Similarly, you can also think of the floor plan as the 7-segment display.)

_ ^ _
O O O
O X O
O O O
O X O
O O * start


1) Left: The guy in the painting is looking forward. If you trace lines of sights of all three paintings, they make the digit 4. Note that the hole in the first room matters here!!!

2) Up: The 6 chandeliers make the digit 6.

3) Right: If you rotate the first grid and overlay it on top of the second grid so that the Os are not overlapping, the Os make the digit 8.

4) Down: The red floors make the digit 2. This is also the path you take from start to finish.

Thus, the final combination is 4682!

Bonus puzzle
===========

After clearing the level, if you choose to "Stay", you will be teleported to the locked room! There is no new information besides the 2-digit lock behind the glass doors. All you see is all there is.

Hint 1:
You need to use the solution from the third puzzle.

Hint 2:
The bookshelves behind are part of the puzzle too!!!!! There is nothing inside, so let's see if you can extract any information from it.

>>>> Solution:
The six sides that surround you represent different even numbers. You get 2,4,6, and 8 from the previous combination, and 12 spaces from two bookshelves. Therefore, the number that would nicely fill in the sequence is 10.

...............................

PS. Because the solution is 10, I need to make the dial rotate down from 9, so you won't accidentally solve the room by rotating it once from 00 to 10 right away.

PS2. I would love to make the final cell match the actual die (1 opposite of 6, etc.), but I was afraid I won't get to publish it.... maybe I'll fix it in the next version.
