Monster Tale/YMMV

Anticlimax Boss: At least relative to the bosses before it, Snout and Priscilla are actually fairly easy, since Snout's attacks are pretty easy to dodge.
Cliché Storm
Ear Worm: The majority of the Kid King's themes.
Designated Villain: Meade and Deanu are never shown doing anything evil, really. Meade just plays music for his monsters, who appear to like it (though he does say that he uses it to brainwash Krubble), and Deanu seems extremely ambivalent to everything and is content to just play with Aquid and swim all day. It's unknown if he even interacts with the monsters on his beach at all.
Esoteric Happy Ending: Chomp unites with his mother and Ellie gets to go home! Except... The two friends split up and might not see each other again. The kid kings are good now, but remain in the Monster World instead of returning to families that presumably miss them. And while Priscilla has been dethroned, she remains in the world where she still has a small measure of political power...
Game Breaker:
- Raising Chomp's Paladin form to get the Healing skill makes the game infinitely easier. Because it's very easy to restore Chomp's stamina, it's basically free (though slow) healing, and can be used to heal yourself up completely at every safe spot.
- Drill Em Mister probably counts as well with the amount of Combos it can get off.
It's Short, So It Sucks: Generally the biggest downside is thought to be the games length. Though going for 100% completion makes the game longer.
Padding: The game's Scrappy Mechanic, which makes travel to one part of the world to another take a while.
Scrappy Mechanic:
- For almost the entirety of the game, the powerups you need next are on opposite sides of the entire game world. This means that you will frequently be travelling across areas you've already been through much more often than you will be actually exploring new areas. This tedium could have been avoided with portals or Doors To Before like most other Metroidvanias have, but, unfortunately, this game doesn't have them.
- Nothing tells you how to unlock Chomp's forms, and at least one becomes a tedious Luck-Based Mission to unlock: you need items that are "surprises" and you can't buy them.
That One Boss: Zoe and Mister Lobster. The difficulty is much greater than that of the previous boss if you don't pay attention to what Zoe does. There's a lot going on at once after you've inflicted 50% damage, whereupon the disfigured bunny starts using a rolling attack (that comes in at the side you're closest to) that gives you barely any time to dodge. Chomp is certain to go down a few times, not to mention Ellie.
