This concept is really well executed! I love the sass from the narrator when you put in a predictable combination like 1-2-3-4 or 4-3-2-1. The idea of being able to re-arrange the rooms in any order has a lot of potential.
If you wanted to keep building, I could see this expanded into a full puzzle game where each level the player gets an additional room. So they'd start with 3 and go up to however many you could. Playing around with the room formation could be interesting as well. Instead of in a line you could do a square or a cross shape.
My only real criticism is that the narrator always sounded a touch to quiet, volume sliders would be nice.
Overall quality game! I had a lot of fun and wish you the best of luck in your future game dev!
