Almost My Floor

This is the first puzzle in the game. In Chapter 1, after dealing with the spider, you need to turn the power off so you can get a crowbar for the elevator.

Talking with Marsha and viewing her mailbox will open up some dialogue and she will give you a guide - once you have this you can attempt the puzzle. It's a basic one if you know your primary colours.
