I've planned that, you will have no doors, but a hiding mechanic similar to the FNaF 2's mask, but it'll only work when a robot is coming from the hall.

You'll have a fence at your front with a room that connects the hall with your office, and the robots will randomly decide if they want to start breaking the fence or try getting into your office, so you'll always need to use the flashlight.

If a robot is at the room after the fence, it will always opt to start breaking the fence if you're hidden, and you will need to fastly shine your flashlight at the fence (more like spam click), but theres a chance that the robot will not go away at first, and it will run at the hall and you'll need to hide.

The flashlight's battery ends fast so you necessarily have to check the cameras to see if any robot is coming.

This post also will work as a guide futurely if you're having difficulty at the game (if anything isn't scrapped).

EDIT: Some robots could also opt by going into the right office hall directly without going to the room after the fence.

Path example ahead. (The red line is the same path from all robots, the rest means random points that they can opt to go.)
