Almost My Floor (EP)

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.
