* AmericansHateTingle: Or rather, Americans Hate [=DeathSmiles=]. They'll accept BulletHell gameplay just fine, but the AudienceAlienatingPremise really hurt sales, due to FanService coupled with characters who are obviously under 18 being seen as "pedo bait".
* AudienceAlienatingPremise: The controversial character designs did ''not'' go unnoticed, ''especially'' not in America.
* AwesomeMusic:
** The Limited Edition Arrange Tracks contains an epic arrange of [[https://www.youtube.com/watch?v=3cGpW03jNjQ Hades Castle.]] Epic yet so faithful to the original, you can even play that song on your console's hard drive before selecting the final stage, [[{{MickeyMousing}} and the song will even finish when the stage is over.]] Improve your score with the PowerOfRock!
** [[https://www.youtube.com/watch?v=gMP7a3nbuKk Burning Halloween Town]] is great as well.
** What theme could possibly be epic enough for a fight against something called "[[FinalBoss Tyrannosatan]]"? The game designers went with a variation on "[[Creator/JohannSebastianBach Toccata and Fugue in D Minor]]". Probably not what anyone was expecting, but ''damn'' does it work!
** The sequel is no slouch in the music department either. [[https://www.youtube.com/watch?v=X73TRQl8JRw Christmas Boss themes]] [[https://www.youtube.com/watch?v=I9qxoXJTGZo never sounded so good.]]
* BrokenBase:
** The English localization of the first game's 360 port. Some English-speaking fans find it disgustingly bad, others are fine with it considering that most shmup players PlayTheGameSkipTheStory anyway.
** Also in that game, the initial removal of a lot of slowdown. Those who have played the Japanese version felt it really added a lot of FakeDifficulty, whole those who haven't didn't really notice or care. Most of the complaints died down when an update patch altered the slowdown back to Japanese version levels.
* FreudWasRight: The blue and yellow suicide bullets in ''IIX'' that chase you are nicknamed sperm.
* FridgeHorror: Sakura and her family entered Gilverado by way of a car accident, making their home in the swamp. In the swamp stage, you see a wrecked van. It belonged to Jitterbug.
* GameBreaker: Sakura in ''Mega Black Label'' has ''two'' familiars, making guarding yourself against suicide bullets much easier.
** In 1.1 Arranged, Sakura's game-breaker status is challenged only by Follett thanks to getting additional control over her baby dragon familiar which happens to be the biggest damage-dealer in the game.
** Sakura is no longer in ''Deathsmiles IIX'', but there are two contenders for her place. First off, Lei has two familiars like she did, with all the accompanying advantages -- although he's less broken, being weaker overall to compensate. Meanwhile, Supe's familiar is the ''ghost of Tyrannosatan'', and she is as stupidly powerful as that suggests -- she's not the best scorer, but if you just want to play an unstoppable juggernaut who hews a path of carnage through anything in her way, you can't beat her.
* ItsHardSoItSucks: See DifficultyByRegion example; it was enough that many players took up threads relevant to the game to rant about it for pages, some calling that particular version of the game an outright PortingDisaster. Amusingly, many of the people making this complaint are ''experienced players.'' Fortunately for these players, a patch fixed this several months later.
* LesYay: Rosa is quite flirty towards Sakura.
** Various pieces of art show the girls being a bit clingy with each other (like the cover, for one example)
* {{Macekre}}: While not to the same extent as Mobile Light Force, there are some very clear changes in the US localization. The characters now have outright horrible clichéd accents.
* {{Moe}}: In addition to her maid outfit, Follett has glasses, a timid personality, and absolutely no nose.
** Greatly increased for all characters in the second game.
* {{Narm}}: Unlike Tyrannosatan above, the BigBad is named Jitterbug.
* NightmareFuel: Rampant.
* TheScrappy: Rosa is dismissed by many fans as being slutty, a theory not helped by the fact that she quite blatantly [[LesYay flirts with Sakura]]. Her, like, ohmigod TOTALLY ValleyGirl accent is not a hit in the West either. Also possibly a TierInducedScrappy, second only to Sakura.
* ThatOneAttack: Whroon's apple attacks, [[{{DifficultyByRegion}} in the US version at least]], as they're all very fast and quite dense.
* ThatOneBoss: [[http://www.youtube.com/watch?v=YW1Gf0Uv3SM#t=1m55s Bavaria, boss of the volcano level.]] He has multiple attack that fire a large amount of stuff from multiple directions, even on level 1 difficulty. [[{{DifficultyByRegion}} In the US version]], Whroon, the boss of the forest level, ascends to this, see ThatOneAttack above.
* ThatOneLevel: C-2, the volcano, and B-1, the forest, largely due to the fact that they are heavily sped up in the US version.
* TierInducedScrappy: Poor, poor Windia. Weakest character of the bunch by far.
** And Rosa and Sakura are godly in contrast.
* ToyShip: [[spoiler: Casper and Lei. In Lei's first ending in ''Deathsmiles IIX'', Casper walks in on him while he is changing clothes. In Follet's first ending in ''Deathsmiles IIX'', Casper hugs Lei from behind even though they are both naked in a hot spring.]]
