* FridgeLogic: If Maria is the housekeeper, shouldn't ''she'' be the one doing the tidying up?
** The [[ExcusePlot plot]] is that ordinarily she would, but the party left the place in such a state that she went on strike.
** Of course, this doesn't explain why Willy doesn't just say "You're fired, now get out of the way so I can get some sleep."
* NintendoHard: Hacks of the game are so hard you have to exploit GoodBadBugs to complete them. Even though ''Jet Set Willy 2'' is completable, it is still a very hard game, requiring pixel-perfect jumping, and you only have eight lives (no extra lives in this game).
* NightmareFuel: That big green face with the star on its forehead on the "The Chapel" & "Priest's Hole" screens.
* SequelDifficultySpike: It's even harder than ''Manic Miner'', as it adds complexity by introducing free-roaming and the screens are no longer isolated, self-contained levels to be completed linearly one by one.
* ThatOneLevel: The words "The Banyan Tree" strike fear in the hearts of old-time gamers to this day. "The Nightmare Room" (just to the east of "The Banyan Tree") also [[IncrediblyLamePun gave players the Willies]]. The worst part is that [[spoiler:there is absolutely no reason to traverse "Banyan Tree". The left hand side goes nowhere, climbing the right side isn't an issue in the bug-fixed version, and you can just go the long way round if you're desperate to get there.]]
