These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Breather Level: The second level of Circus Park compared to the rest of Circus Park is easier, theres not as much hard platforming that made the first level of Circus Park hard it mainly has straighforward fighting enemies in it, it's also ridiculous that the second level also has the game's easiest boss in it.
Likewise, the third level of Blizzard Castle (where the objective is to make the head of a snowman), is relatively simple, takes place in a small area, and doesn't feature many enemies. It comes as a welcome relief after Moles.
That One Attack: Most of Dark Corvos attacks arent too tricky to dodge but when he summons the Saltim shadow clone and when Dark Corvo clones himself and attacks you is when it really gets difficult.
That One Boss: Moles the walrus, he first starts by ice skidding towards you which is easy to doge but then he rolls into a sphere of ice, and very rapidly starts bouncing around the room, and this attack is very unpredictable, also to make matter worse every time he hits a wall, small ice spheres appear and start bouncing around the room with him, eventually he will stop and allow you to hurt him but those ice spheres are still bouncing around, and while your focusing on hurting him, those ice spheres can hit you, stunning you for a second, and he will repeat this process for the whole fight.
Dark Corvo the crow sorcerer is even worse, a lot of his attacks are extremely hard to dodge, for example his shadow clone of Glur shoots homing bouncy balls, his Saltim clone rapid fires bombs at you, which are very hard to dodge, also when Dark Corvo clones himself and attacks you, he attacks at high speed, and there is no clue as to which is the real one, and if you don't hit the right one fast enough he will repeat the attack, it is especially painful that Dark Corvo comes after one of the hardest levels in the game. He's so hard that the game actually warns you he's gonna be hard, and this is a hard game!
Toy Ship: It seems a decent amount of people in the fandom like the idea of Billy and Rolly. Sadly, the only thing that gave any kind of Ship Tease was a 2 second clip in the opening cinematic.
Vile Villain, Saccharine Show: If not a Crapsaccharine World, it could be inferred that this game is an example of this trope, as it was Dark Corvo who summoned the Crows to Morning Land in the first place. Also, it was purely the intention of Dark Raven to plunge Morning Land into eternal night.
