* SugarWiki/AwesomeMusic: As always with Sunsoft games, the soundtrack is fantastic.
* CultClassic: It's considered a well constructed, but criminally overlooked MetroidVania for the UsefulNotes/{{NES}}.
* SugarWiki/HeartwarmingMoments: The PAL English translation's ending: Bop-Louie initially leaves on a rocketship back to his home planet, but immediately returns because he realizes how much fun he had with his new friends. The text then says the four had numerous adventures together forever after. Awww.
* NauseaFuel: You see those white ropes that dangle from floating platforms and that you use all the time? They're the platforms' drool (or possibly mucus)... Yuck!
** The fact that Shades' special attack is to hit himself on the back of the head with a hammer, making his [[EyeScream eyes fly out]] and kill the enemies, can come off as this.
* PopculturalOsmosis: The [[https://www.youtube.com/watch?v=f9JOXD4szwc tundra theme]] is used in the better-known ''[[Webcomic/MegamanSpriteComic Megaman Sprite Game]]''.
* PortingDisaster: Unfortunately, the Wii/Wii U Virtual Console release uses the PAL version, which means the gameplay is unnaturally sped up and the music is faster and played at a higher octave, sounding distorted in the process. Also YMMV on how this version replaced two of the main characters.
* ScrappyMechanic: In 2024, ''Herebeke Enjoy Edition'', an UpdatedReRelease of the Famicom original, was released internationally. However the conversations were not translated from Japanese, and instead of using an English overlay, the developer chose to include screenshots of the same conversations from ''Ufouria'' as unlockables in the gallery, making translation a hassle.
* ThatOneBoss: The underwater mini-boss you fight with Gil. It moves much faster than you can and takes up a lot of the rooms space, it can float in any direction after you, and Gil's only means of fighting it is to stomp it from above and then grab a ball it drops, and if you go right down to get it, it leaves you a sitting duck for it to float right down onto you, and balls fade away after a few seconds, so you're short on time to grab it and throw it at the boss. It is ''very'' hard to fight this boss without taking some damage from colliding with it.
* VindicatedByHistory: It was only moderately successful when it was first released and got decent but unremarkable reviews. It got some sequels, but only in Japan (and none of them were platformers like the first game). It wasn't until it was re-released on Wii Virtual Console that it gained a cult following in other parts of the world, finally getting [[VideoGame/Ufouria2 a proper sequel]] in 2024.
