Got a key and steamed up a mirror. There are lots of codes needed.

[Mistery]

Got

key, note A with math on both sides, note = with math, and a strange transparent rectangle with possibly numbers on it.

for the math A, B, C, D

I get
A=9
B=? (don't know)
C=4
D=3

Stuck.


EDIT
For mirror

follow the arrow to open up a panel in the wall

[EscapeGirl]

I'm right where you are, Mistery. Only I am not sure how you figured out the letters... (Math isn't my thing...)

Can't

Get into the shower, either.

[Mistery]

I can't access shower either.

My ideas the math:

For A: if you put the left column into the middle, you get 9=?, so I think it's 9
For B: no idea
For C: 5+2+6=13, and 1+3=4
For D: -2 then /2 then -2 then /2 again etc.

For the letter equation:

I get 7 for the first line
and 8+z (while z=b which I don't know) for the second line

EDIT
Okay, brute force for the rest worked
Code for first door on the right

713 (so b was 5)

EDIT2
Now in bedroom.
Found note, and

managed to place transparent sheet on the drawing

Used

blue key, got some strange clues (seems to have to do with drawing), and a flashlight

Progress!
2nd left door:

use the clues from the picture with the house as color clues. Apply it to sequence seen in the drawer. Enter this color sequence

Now in kitchen. Found

card, torn note, green key, box with button passcode (don't know code yet), and knife

Is the

writing on the fridge a code for a door?

Used green key

in bedroom. Got another card, and there is a slider puzzle

I think that the code for the door straight on might be

what is written on the fridge. Just can't enter those letters right

[Uncle Rim]

There's not too many colours in a black and white drawing. All I can gather is the sun is yellow and the bottom 3 might be green.

[Mistery]

yes, sun is yellow, grass is green.
Find color for sky, and for roof

[Uncle Rim]

There is no black for the sky!

[EscapeGirl]

Hmm....I think it's too late for me to think clearly. Almost 2 a.m. I may come back to this game later. Thanks for the help!

Lol

Okay solved slider puzzle, and this is the clue/code for the chess code. But

I have tried all possible steps from the field shown, nothing works so far
