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.
YMMV: Dust: An Elysian Tail
Awesome Art: The game looks gorgeous, even during its development it looked amazing.
Awesome Music: The music for the game as a whole is stunning. It gets better as the soundtrack was released at HyperDuck SoundWork's Bandcamp page for a minimum of £5 GBP (roughly $8 U.S. Dollars)! And in lossless formats, to please the audiophiles.
Anticlimax Boss: General Gaius. Aside from being able to parry far more often than is reasonable or fair, his attacks are fairly telegraphed and easy to dodge, and his magic attack in the latter two rounds will detonate harmlessly as long as you let him fire off all three.
Broken Base: Depending on who you ask, Fidget (and her voice acting) is either an awesome sidekick, or akin to Navi.
Cliché Storm: Expect to hear about "souls" a lot. Expect to hear about one's "essence" in the "Life Thread." Expect to hear about "the forces of good and evil" and about how "your choices make you who you are." Don't expect the story to evolve into anything more than a straightforward battle of good versus evil. Don't expect the hero's morals to be challenged.
The wizard in the Sorrowing Meadows, especially if you've focused on upgrading your own attack power instead of Fidget's. The wizard teleports to avoid your strikes while constantly summoning zombies, including exploding zombies that can easily be beamed right on top of you. Only Fidget's attacks can cause any harm, so you have to spam it constantly.
The occasional yeti encounter in the Blackmoor Mountains. They carry a hammer and use wide swings that can easily connect, they aren't stunned by parrying, and they're incredibly tough. The flying Dust Storm is really the only the reliable way to stop them, and they can even knock you out of that if you're not careful.
The Fidget stat eventually becomes this. Unlike with the other stats, there are numerous items that will multiply the Fidget stat rather than add to it, and they all stack. By the end of the game, the Fidget stat could be four times the second-highest stat. This makes the room-clearing Dust Storm attacks obscenely powerful.
Only a couple of enemies can attack Dust while he is spinning through the air spewing Fidget's projectiles, simultaneously attacking, defending himself, and sending out a cloud of enemy-tracking death which puts them in hitstun, allowing Dust to attack them normally, which recharges his magic meter and cools down his spin attack, allowing him to rinse and repeat indefinitely until the enemy is dead. Even the enemies which can hit Dust out of this attack are still best dealt with in this manner, because the projectiles put them into hitstun, preventing them from attacking - you just have to make sure you get them in hitstun before you move in, whereas against many enemies you can simply fly over them recklessly. This strategy is also effective against all the bosses, including the final one - indeed, it is fairly easy to avoid being struck by the final boss at all the first couple times you fight him, and even when he throws magic at you, it is still not terribly difficult to avoid and he is still best dealt with via projectile spam.
For pure melee, the aerial slash and smash combo lets you chain any enemy into an unbreakable cycle of harm. The smash also sends out a shockwave that knocks enemies back, so groups are just as vulnerable. This is especially useful against flying enemies.
The wasp monsters in the Sorrowing Meadows. While not overly tough, they appear in groups, their nests regularly spawn more unless under constant attack, and destroying the nest produces four more. Add onto that their quick attack which can easily catch you when you're trying to take out them or others out.
Soldiers. They're not particularly dangerous. What makes them annoying is that they can parry your attacks, and in groups they tend to do this quite a lot.
Good Bad Bug: Naturally, items that you sell to a merchant are normally removed from your inventory, but if you sell a stock of items within the multiples of 256 (256, 512, 768, 1024, etc.), the game glitches out, you keep the items and you make money off of them.
While it doesn't have nearly as much of an effect thanks to the fact that any combo bonus exp is scaled to your level and thus a 5-hit combo on level 1 gives you 20 bonus exp or so while doing one on level 20 will net you closer to 1000 exp, you can also perform infinite combos with little effort in one of the mansions in Sorrowing Meadow. This involves luring one of the necromancers near one of the pillars with a slidethrough gap in the bottom and positioning Dust between it and another one: if done correctly, the necromancer will endlessly summon zombies inside the pillar where they're unable to hit you (even the exploding zombies won't harm you, even if you're close enough to them where their explosions would normally be able to hit you) and break your combo, allowing you to tap a button leisurely to keep hitting them with the Dust Storm.
In at least the Xbox version, it's possible, with the right timing of two air hits while facing one direction followed by an air dash in the opposite direction, end up very slightly higher than when you started. If you do it again immediately (turning back around to air attack in the same direction as you did the first time), you end up very slightly higher still. Sufficient spamming of this allows you to, albeit very slowly, Sequence Break to places that you are intended to need the climbing, double jump, or super jump power-ups to reach.
The scene when you return Reed's box. One could not be faulted for assuming at first that Dust is merely being sarcastic about the evil spirit sapping his life energy.
The animated cut scenes near the end are not as high quality as most of the game's art, which sometimes makes taking them seriously harder.
At the end of the final boss battle, when General Gaius is dangling from a ledge in the volcano; what's so Narm-y about it is the way he keeps screaming "CASSIUS!" Even given the circumstances, it sounds overacted.
That One Achievement: The Stuff of Legends, which requires earning four star rank in all Arena Challenges, some of the arenas requires VERY precise jumps and even to be overleveled to hack through waves of monsters and make to the finish line in time.
