* SugarWiki/AwesomeMusic: The soundtracks of this game and it's follow-ups.
* GameBreaker:
** In the first game, we have the [[FireBreathingWeapon flamethrower]]: Used correctly, it's capable of wiping out any kind of opposition, and works wonders on bosses.
** [[LethalJokeCharacter Q]][[OddJobGod P]] in ''Acceleration of SUGURI'', to the point where she's banned from competitive play.
* LesYay: Is there ever?
** While all of the girls have their moments, Suguri and Hime are easily the most noticiable, jokes of rainbow-coloured circles and chains aside. The original game's ending in particular springs to mind, with Suguri [[spoiler:smiling for once, offering her hand to Hime and welcoming her to earth, with Hime answering " I'm back (home)". Cue the poem about finally not being alone and two of them holding hands as The End is shown.]] D'awww...
** In her extra story in ''Acceleration of SUGURI'' Saki says that Kae has a nice body even if she's a little dense.
--> '''Saki:''' (On defeating Kae) ''"Waaah... Kae, settle down!"''
* [[MorePopularSpinOff More Popular Spin-Off Sequel]]: ''Acceleration of SUGURI'' and ''[[ExpansionPack X-Edition]]'', largely due to being a {{fighting game}} oppose to as a [[NintendoHard tough-as-nails]] [[ShootEmUp shooter]]. Not even [[TheComputerIsACheatingBastard a dirty fighting Suguri]] could sway a non-shoot 'em up fan from it.
* PortingDisaster:
** The initial Steam release of ''Acceleration of SUGURI X-Edition HD'' was released in an unfinished, buggy state. Steam users has reported the game frequently crashes, the online multiplayer is bugged or non-functioning, compatibility issues with Windows 8/8.1, screen flickering problems in fullscreen, and broken Steam Achievements, among other things. The DRM-free version released in select Indie Royale bundles also had similar problems. A patch was released to address some of these issues in 2014 but only for the Steam version, which also introduced [[LoadsAndLoadsOfLoading frequent and extended loading times]] between matches which wasn't present in the original SD version of the game in both English or Japanese releases. It also hasn't been future-proofed compared to other PC games as displaying the game with resolutions above 1080p since this port's release (e.g. 1440p or 4K) [[GameBreakingBug will cause the game on boot]].
** The [=PlayStation=] 3 version of of ''Acceleration of SUGURI X-Edition'' also has an issue where the camera has a difficult time of keeping characters in view during hectic moments which wasn't apparent in the original PC version as it can zoom out if players are further apart from each other.
* ThatOneBoss:
** Nanako in ''SUGURI''. She loves to spam bullets, mines, ''and'' the occasional barrage of laser spamming and homing missiles, giving you little room to move around in or defend against, and her hyper attack throws almost everything at you in a storm of pain.
** Robo in ''Acceleration of SURUGI''. It takes up a huge amount of space around the arena, fires off a barrage of lasers early in the fight, and as the fight advances, it fills the arena with drones that flood the area with bullets and eventually it'll start unleashing its WaveMotionGun that deals heavy amounts of damage, even if your Heat meter is at 0%.
* TheyChangedItNowItSucks: Keiko Sakurai's version of the character art and the UI in general for the English version of ''Acceleration of SUGURI X-Edition'' by Rockin' Android for Platform/{{PlayStation Network}} was not liked by some ''SUGURI'' fans, although this was due to a large part of Sony's ExecutiveMeddling. At least the artstyle is optional in the HD version on PC.
* UnintentionalUncannyValley: QP's new character art, due to the more realistic proportions in the HD versions of ''Acceleration of SUGURI'', is a little uncomfortable.
