Below is my complete level blockout. It's a very simple, but still effective, layout. The player starts in the hallway on the left side, then attempts to walk over to the door on the right, but is blocked by the trap. When they walk back, the upper door will open and allow the player to enter the top room. The player can then also go to the bottom door, which will open as well, allowing the player access to the bottom room. Here, the player solves the puzzles to disarm the trap and finds the key, and then they can go through the door on the right of the hallway.
The main hallway features three doors. Every system in the hallway automatically triggers; when the player walks too close to the trap, the spikes shoot up. When the player walks near the left or the right door, it'll open, allowing the player to go in.
The left room is a patient room of some sorts. It has the number pad on the desk and the key on the floor next to one of the beds. The correct numbers can be found through the entire room; the correct order is from the left of the room all the way to the right.
The right room looks more like a science lab. The pad with the buttons is near the tubes. The player can click on the buttons to change the colors of the tubes. The correct colors are found on the opposite side of the room from where the tubes are; each correct color lines up with its corresponding tube.
