In order to get the level working, I'll have to add some coding to it. Below is a list of all the coding I'll need to do in order to make this a functioning level environment.
Spikes are triggered when the player walks near them
The spikes go down every time the player solves a puzzle
The two doors to the rooms open when the player walks near
The player can eventually leave through the exit with the key
The player can press in a code on the number pad
When the code is right, a green light will show the player's success
Later added: The player can interact with the collectible found in the room
The player can press the buttons to change the tubes' colors
When the colors are lined up correctly, they'll all turn green
Later added: The player can interact with the collectible found in the room
