It’s impossible to create a single, direct playthrough since the order of the sections per floor seem to be randomly generated per playthrough, as soon as you get out of the vent. Each room will always have some sort of marker or identifiable landmarks that will lead to special rooms.
For your first playthrough, it’s better to take your time and look for specific rooms and landmarks to unlock achievements. The solution for each puzzle will always be the same.
And for the final tip, follow the red wires on the floor! These wires will lead you to the right direction. If there are no wires to be found, take note that you can easily find them in hallways!
