Even if you go out of your way to use your favorite characters or try to use elements it just becomes slower but not harder. There's almost no reason to use the League of Extraordinary Accents. This game SCREAMS to have something like Lufia II's Ancient Cave where you can get some thrills with those mechanics. The fixed level system really works against it.
There's potential in there, but it feels like most of the mechanics shy away from using it.
Also, despite the music being great, the battles and boss battles reuse the same theme 99% of the time, which gets tiring fast. And the regular boss battle theme happens to be the worst track in all of the game (DU-DU! DUDUDUDU-DU-DU! pirori pirori pirori~ DU-DU! DUDUDUDU-DU-DU!)
But the worst part is the freaking dwarfs trying to give you the eco-friendly message about how humans are destroying the environment and whatnot...despite humans not even being industrialized in all of El Nido (except for those guys outside of time) and they say that while committing genocide against the fairies with heavy smog-spewing machinery and tanks. Like give me a break... Every human settlement in El Nido is comfy nature-friendly villages and you are giving me the talk while riding a freaking tank.
