My level and coding step by step:

Character starts the game in the cell and hears a scream. The doors are open. Time for the player to escape.

The player is then introduced to the clocks, one of which shows the lever.

Once the player clicks on the lever, the item will pop up near the players camera. 

Player places the lever and uses it to open the elevator doors.

Once inside the elevator, the music begins to play, then pressing the red button will activate the elevator to move down. Once on the bottom floor, the player will hear the bell sound. 

Finding out that the exit is locked, the player will enter a room where a strange set of eyes are watching. One of the eyes is the button that will activate a door to the computer room.

Then in the computer room is the red button that will activate the exit door to open. 

The player goes out of the building where the walking simulator ends.

For the coded objects, my total count was four. First was opening doors. Second was the lever changing positions (the clocks, to the player, to the bottom part of the lever). Third was the elevator, which I used animation in order for it to move downwards. Forth was the buttons used to trigger the doors to open.  It should also be mentioned that I had a few texts to guide the player on what to do or what is happening. As well as having some background music and sound effects to give the game more of an atmosphere.
