History YMMV / MonsterBoyAndTheCursedKingdom

* ThatOnePuzzle: Opening the corked well in the village of Lupia. It's a series of MoonLogicPuzzle that'll make you look over every nook and cranny in Lupia unless you read a walkthrough. It's completely optional and the rewards are relatively trivial (a SoundTest menu, a very short BonusDungeon, and a single Life Heart), but it's still required for HundredPercentCompletion.

** The elevator music in the tower between Lupia Village and Aerie Village sounds very similar to the stage music of the original VideoGame/WonderBoy.

** The Haunted Manor is where the game really goes to town with puzzles. There are many that are not-so-obvious to figure out and a few that have pretty damn obtuse solutions not to mention a rematch with Malino that can also be annoying and difficult. Most enemies in the Haunted Manor also hit like a truck to make matters worse.

* DemonicSpiders: Bats in the forest level. Since you're stuck with Pig form only which has a terrible jump, horrendous attack box (only an inch directly in front of him) and limited magic attacks, bats which have a random move and attack pattern can make you want to pull your hair out. It's made only worse by the absence of the teleport rod, so you can be stuck with no magic attacks and no way to buy more. Bats alone have made more than one player ragequit the game for good.
** However you can just mash attack and let them dive into your fist, as the Pig form allows you to easily mash it.
* GoddamnedBoss: Uncle Nabu. He's a PuzzleBoss (you have to make him drink water instead of wine). But the problem is, before you can reach the puzzle part, you have to cause the slot machines to line up. This isn't as daunting as it sounds as it's a simple timing - but your timing must be ''perfect'', and you have only two chances before Nabu gives you an attack you have to withstand. Fortunately [[AntiFrustrationFeatures if you do poorly enough, they start throwing hearts at you]].
* ScrappyMechanic: The game is ''very'' stingy with giving you hearts, and since save points often keep you at only three hearts minimum, that can be as many as [[GlassCannon two or even one hits]] from any kinds of hazards unless you're able to backtrack.
* SpiritualSuccessor: To ''VideoGame/WonderBoyIIITheDragonsTrap''.
* SurpriseDifficulty: Once you get the Frog form, the game becomes a lot harder. You need to update your armour or else you take crazy amounts of damage. The problem is, the armour, shield, and new weapons cost at least 350g a pop, and you've likely spent most of your money maintaining all the magic for Pig form. You also don't get a reliable way to make money until you begin the volcano.

** The Undead Wizard is a frantic boss who onstantly throws things at you, and forces you to use the unique-to-that-dungeon mechanic to remove its shield.

* SuspiciouslySimilarSong: The music that plays in the Castle of Lupia's interior bears more than a slight similarity to [[VideoGame/CastlevaniaLamentOfInnocence "Lament of Innocence"]] from the eponymous ''Castlevania'' game.

* ThatOneLevel: The volcano. For one, it goes on [[MarathonLevel forever]]. Two, despite having a branch of four paths, it actually has a specified order. Three, once you get the lava boots game is [[HitboxDissonance very picky about whether or not you're touching flames or not]]. Remember that even ''with'' the Ice Armour, enemies will take at least one and a half hearts away upon impact, and lava will be even more dangerous. There is also a part where you have to freeze a lava-flow and then jump through it before it melts the ice blocks. Better have quick reflexes.
