* AntiClimaxBoss: Suprisingly, Walpurgisnacht. Her attacks are powerful, but easy to avoid, especially if you're a character with a dive attack and can just hang out in the corner constantly hitting her. The challenge is getting through the enemy packed stage quickly enough that you've got enough soul to last the fight.
* FridgeBrilliance: Mami's special attack. [[spoiler:It was the same attack she used in the anime before she died.]] In the game it leaves her with barely any health, and can be prolonged to temporarily leave her a OneHitPointWonder for extra damage.
** Kyouko's barrier is basically useless... unless you're fighting Oktavia, in which case it's one of the few reliable ways to handle her.
* FridgeLogic: Noted by Gesh86 in his LetsPlay of the game: The most likely reason for getting the [[spoiler: "Homura wakes up in the hospital and tries again"]] ending sequence is that ''Homura'' [[KilledOffForReal lost all her Soul Limit]], as the rest get special endings.
* ThatOneLevel: H.N. Ellen/Kirsten. The other four levels are a fairly straightforward progression of more and more powerful [[{{Mooks}} Familiars]] and [[BossFight Witches]] with harder to avoid attacks. Kirsten, however, has a Labyrinth full of {{Bottomless Pit}}s, other stage hazards, and LedgeBats - while ''none'' of the other Witches - not even the ''final boss'' - use stage hazards (unless you count WPN's rain of debris). This becomes even more infuriating when you remember that [[GameplayAndStorySegregation in canon, Kirsten hardly has a Labyrinth and gets killed in about 30 seconds; she mostly exists to show off]] how {{Badass}} the newly contracted Sayaka is via LookWhatICanDoNow (though FridgeBrilliance might kick in when you realize Sayaka is the best character for this stage).
* TierInducedScrappy: Mami and Sayaka, for the inverse reason: Mami for being too weak compared to the series, Sayaka for being too strong.
* WildMassGuessing: H.N. Elly/Kirsten was a gamer when [[spoiler: she was human]]. This is why she has two Witch names; one is a screen-name. Combined with this, the Labyrinth full of [=TVs=] is a dead giveaway. This is also why her stage is full of ClassicVideoGameScrewYous: MediumAwareness + GenreSavvy + Witchy angst and hate.
** Almost certainly intended by canon: [[MeaningfulName HN is Japanese slang shorthand for net handle]].
** In any scenario where Homura's Soul Limit is depleted, it was AllJustADream.
