Cool concept. The player can figure out their own system that makes sense for them. I just put numbers and crossed out the wrong ones with a big red X.
I had trouble figuring out how to open the doors at first, was pressing E and reading the description.
I think E or right click would be better for opening the doors rather than having to aim on the door knob. Another small quality of life update would be using numbers to change the colors.
I found out you can spam click the knob to skip a few rooms. This was useful actually since it got very repetitive to go through every iteration every time.
It was quite anticlimactic winning with spam clicking tho.
Interesting game. I wonder if some other elements could be added to make it less repetitive and more engaging.
