These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Teenage Mutant Ninja Turtles: The Arcade Game
Surprisingly Improved Sequel: The NES version, despite its previous game was a TMNT game In Name Only, had characters from the show, ranging from: Bebop and Rocksteady, Granitor, to General Tragg, had a very fluid battle system and set the stone for the next two TMNT console games.
That One Boss: Krang, he takes way damage than anything before him and will hit you with a kick attack that does a lot of damage and has a lot of reach whenever you get near him, meaning about the only reliable way to hurt him is with jump attacks.
