I passed the game. But code for the chest with heart was bruteforced. And even having the code i cannot understand the logic. I see words (Silence,Colors...) in the letter and tried different variations with paintings in the book and on the wall, but still cannot get it.
ah ... In the letter the last line .. In darkness you will find the truth ... After turning off the light you would find the code ... And comparing the words with the painting tags ...
