The section about "impossible" architecture made no sense. It got to the point that I looked up the solution and the solution makes zero sense. Even before that the second crosswalk one didnt make sense either, the upper left had a clearly visible crosswalk on it but apparently it doesnt... for some reason. So maybe working those out to make more sense would make it better. One other thing I can suggest is put something next to the checkmarks in each box to remind players of the commands UL UC UR CL M CR LR LC LR for example. I think thatd help a lot.
