History YMMV / HenryHatsworthInThePuzzlingAdventure

* CheeseStrategy: You can actually turn [[ThatOneBoss The Captain]] into a [[AntiClimaxBoss complete joke]] if you fill up the Puzzle Meter and activate Tea Time, before using the Golden Robo's laser attack to completely demolish their HP meter as [[https://www.youtube.com/watch?v=43tPcchyUHU seen here]].

** The final boss can be made far more bearable if you shoot at its hands during its projectile spread attack and charge up your projectiles using the Puzzle Realm. In Gentleman Mode, this will allow you to cut through its high HP quicker and get you to the next phase in less time.

* DifficultySpike: The game becomes much harder starting from the second half of World 3/beginning of World 4 and it doesn't let up. And if you're intending to take on the [[BrutalBonusLevel secret levels]], the entirety of [[HarderThanHard Gentleman]] [[NewGamePlus Mode]] or heaven forbid, [[BreadEggsBreadedEggs secret levels during Gentleman Mode]], then ''god help you''.

* SuspiciouslySimilarSong: The Puzzle World's theme is a take on the classic StandardSnippet "Happy Go Lively." Also the first 8 seconds of Go, Go, Golden Robo Q uses the StandardSnippet "Turkish March" before using an original rock and rock theme.

** In Gentleman Mode, the attack where the junk platforms rise upward while energy balls rise from the centre becomes this due to [[spoiler: The Machine's]] far higher HP total, ensuring that you'll be feeling the pressure to deal enough damage or be crushed to death.

** The fight with Weasleby in Level 4-3 is easily the hardest of all the encounters with his hat mech. For starters, it can use a tractor beam to lift up platforms which will hurt if you're misfortunate enough to get stuck in it. And then there's the crushing attack which temporarily takes out one of your platforms. To make things worse, the fight is actually a SequentialBoss where you have to fight a second mech afterwards. The second fight has you dodge purple energy balls which require proper timing to avoid them unscathed, buzzsaws emerging from the left or right which require you to duck to avoid them; the variant that has both saws come out is the worst because you can't attack at all until the attack finishes. After losing enough HP, the mech will drop large pylons which drop onto the ground and either fall left or right. The only attack that can be considered easy is the one where he summons his henchmen to attack while protecting himself from damage until you defeat them all. Oh, and if you lose all your lives, you have to do the stage from the beginning to attempt this fight again.
** [[spoiler:[[FinalBoss The Machine]]]]. Obscenely high health, attacks that affect ''both'' screens, and those ''OneHitKill attacks'' (see ThatOneAttack above). Worse yet is that you have to go through [[spoiler: a rematch with Weasleby (who thankfully has ''much'' less health, as he's a TrickBoss.)]] And if you're fighting it on [[HarderThanHard Gentleman Mode]], then you better have gotten all the suit pieces or else you're for in a ''very'' rough fight to the finish.

** Level 4-? (Secret Level 1) It's an AutoScrollingLevel so you know this can only end well. You're made to deal with the [[StuffBlowingUp red mooks running at you]], use of the Puzzle Realm to create platforms and later on,[[MookMaker Puzzle Mothers]] summoning their spawn in addition to timed jumps with the aforementioned platforms. After that, you have the Hatstacks taking up space on the platforms you need to move on, before combining their placement with moving platforms. After that, it's dealing with the Puzzle Mothers on moving platforms, and useage of the Puzzle Realm to block their spawn, who ''will'' ensure you fall to your demise. The final section is more of the same, and if you fail then its [[CheckpointStarvation back to the start for you.]] Completing this hellish trial unlocks the Gentleman's Vest, which you'll only really need for lava levels.[[note]]Specifically the one secret exit in World 3-4 due to it requiring you to dive into lava.[[/note]]

** Lady D is the first boss of the game. [[EarlyBirdBoss And what a difficult boss she is.]] Each boss has a unique Puzzle Realm gimmick; hers is shooting beans that sprout and make you unable to move the blocks above them, also serving as a hazard should they reach the top screen. Not to mention her minion summoning, machine-gun attacks and [[BossArenaUrgency destroying part of the arena,]] [[OneHitKill potentially killing you if you fail to dodge.[[note]]And no, using the Golden Suit will not save you, because the attack can still kill you.[[note]]]]

* ThatOneBoss: This game makes a good work of lacking ridiculously easy bosses aside from [[BreatherBoss Lance Banson]] or [[spoiler: Weasleby himself.]]

After that, it's dealing with the Puzzle Mothers on moving platforms, and it's likely that it's mooks will ensure you fall to your demise. The final section involves using the Puzzle Realm to block the mooks sent out by the Puzzle Mothers and if you don't time that well, then it's back to the start. Completing this hellish trail unlocks the Gentleman's Vest, which you'll only really need for lava levels (specifically the one secret exit in World 3-4 due to it requiring you to dive into lava).
** Level 4-? (Secret Level 2) has ice physics platforms and all your enemies on it. Enemies that can fire projectiles or spawn several smaller henchmen to ruin your day. It's also the only level in the game to make the multicolour puzzle platforms into a nightmare due to their usage in sections where you only have a limited time to make them the same colour before your current platform crushes you into the ceiling. That's not even counting the section after the MultiMookMelee involving moving platforms that can crush you to death, or more sections involving precise platforming where you have to climb up conveyor belt pillars and across smaller platforms while dealing with more projectile enemies.

* {{Speedrun}}: A Youtuber named Judge Fish decided to do a speedrun of this game and [[https://www.youtube.com/watch?v=M04BFNotK7I discovered a glitch that allowed the player to resurrect themselves.]]

* ThatOneAttack: [[spoiler:The Machine's]] OneHitKill attacks, especially the one where it summons walls to crush you and you only have a few seconds to destroy the buttons on them before the walls crush you. Ironically, it's one of [[spoiler: The Machine's]] easier attacks in Gentleman Mode due to the buttons low HP, though if they're placed high up, the attack can still trip you up. Expect to see this one a lot.
