@FEIK Drag the letters from the Boiler/Storage to the Transmutator (a.k.a Transmutate Green Thingy) and when you have 2 letters there press Transmutate, then you get a new letter.

I've found it, you need to go to the bar with Annie on the first day, then cheat on your wife when you got the chance, she will take Molly to her mother's house.
The day after that you have no choice but going to work, note that I didn't saw the killer to kill me or something, just everyone were dead at the lab.
Went to the roof, after picking "Give up?" it gives you an option to "Jump" and then you just stand still, close your eyes and the game is over (dead again), no good endings in this game.
Found Typo, on the stats when you level up, on Hairy Knuckles, it says "Strenght" instead of "Strength", might occur in different locations but I didn't check.
