You know, my team is pretty intimidating. You're just lucky I'm using a mere Tentacool at the moment instead of King the Noctowl. Edit: While it isn't inherently a "puzzle", the worst in my opinion will always be those dreadfully long HM Flash caves. I'm looking at Gen 1 here.
Honestly i think the worst puzzle is the puzzle in the ice gym in Diamond and pearl
I definitely think the Snowpoint Gym Puzzle is bad, manageable since if you know what paths to take it’s straightforward but still bad.
