Here is my basic room escape puzzle design. It is a simple color combination puzzle. The player needs to input a combination of colors that flashes on the elevator button into a box in the corner of the room. Once they do that a key (simple geometry cube) will appear. The player will place the key in a slot on the elevator panel after which the elevator will function and they can leave the room.
Awesome job, well done for taking the time to plan this out and share it with us.
