After using matchsticks on the map it revealed the no.s and patterns but was not able to understand it and was not able to open the main door with password. Please help.
Took me a while as well. Go back to room where you found peanut butter. There's a light switch on the wall. Keep playing around with that switch and the ones in the room with the safe until it glows orange like the safe room. If you found the code for safe you'll know what i mean.
the first symbol is L since the shape of the symbol is L with a dot in the corner, and the letter L is in this shape, thus the first number of the code is 7
