good question! that’s partly because i wanted the format to be consistent (i.e. have the same number of puzzles on each separate page according to the original pdf)
another reason (spoiler warning) is that i wanted to keep the main twist a secret from players that look at the solutions before discovering the mechanic. “Overblock” by xxuurruuii actually uses this method to get the message across too! that’s why there’s a repeat of the whole puzzle in a different order in the end haha
