- Demonic Spiders: The jumping toads, of course, being Castlevania´s fleamen distant cousins. They act the same, jumping frenetically around you. They are incredibly fast and can tear your life apart quickly if you cannot kill them as soon as they leap at you.
- Fridge Logic: How come Zangetsu obtains Crescent Moon, a circular slash technique, by killing Miriam, and Blood Moon, his Double Jump, by killing Alfred? Miriam's main attack is a straightforward whip, and she cannot attack in arc without her axe subweapon. Her unique feature is that she can jump higher than anyone else, which would've translated well to Blood Moon. Meanwhile, Alfred has no special mobility ability of note, but his basic attack is him swinging his staff in an arc, which then would've fit Crescent Moon. (At least with New Moon, it makes sense since it's a sprinting technique taken from the only character who can dash, even if not in human form.)
- Game-Breaker: Frostcalibur + Axe combo pretty much annihilates every boss in the game short of the final boss. Frostcalibur works on bosses but doesn't result in a One-Hit Kill like normal enemies; however, it creates an opening long enough for you to get a hit in with Miriam's Axe, which is the highest single-hit damage in the game and is normally Difficult, but Awesome until you add Frostcalibur to keep bosses in one place for you, and as a bonus, frozen bosses take double damage from the next hit. This also takes some doing in both finding and maintaining both subweapons (as others may be more practical in parts of the stage), but in the Boss rush mode, this is a moot point as you can select what subweapon you want.
- Genius Bonus: If you know about Ars Goetia, you may understand why the bosses are designed as such in the game (even though some liberties are still taken). Example: The Goetian demon Focalor commands the seas, so what does the Focalor boss do? Why, try to kill you with water, of course.
- Good Bad Bugs: Zangetsu's Crescent Moon can sometimes hit twice, due to the hitbox of the attack hitting multiple parts of the victim's hurtbox. This is most easily accomplished by attacking during a forward jump.
- It's the Same, So It Sucks: A common critical complaint is that the game is almost a bit too similar to the game it's an homage of, and doesn't do enough to try new ideas.
- Porting Disaster: There have been a few fans who complain that the game's 3DS port is susceptible to lags and frame rate drops.
- Signature Scene: Perhaps the most memorable scene from the game is the fight against the True Final Boss in Nightmare Mode, Corrupted Zangetsu. Not only for the situation itself, but seeing the power of teamwork at play makes this already awesome boss battle truly stand out.
- Tier-Induced Scrappy: Alfred. He has no real mobility, his normal attack is terribly short ranged, and his health pool is pathetic. While he can cast magic and has a decent mana pool, it's better to just cast and change to a better character, since the spell doesn't disappear if you do switch.
YMMV / Bloodstained: Curse of the Moon
