The last two fights, but the final fight especially on "hard" difficulty is far too unbalanced and just drags on forever.
The major problem being that the enemy boss teleports on set locations which are chosen somewhat random (mostly near you) which can really screw you over.
The second big problem is that he can cast very large red beams that do a lot of damage with very narrow beams, or deploys bombs around the arena that do a lot of damage, which wouldn't be that big of a problem if you could run or at the very least not crawl. That's right your character has no idea what running or even walking means, he can only move at a snail's pace.
Thirdly the boss also spawns far too many enemies (especially towards the end of the fight), while also expecting you to fight and dodge the bosses attacks (which mostly do a lot of damage).
Fourthly the battle drags on for so long because most enemies, and the boss especially, are bullet sponges and it takes forever to kill anything.
In the end it becomes more a matter of dumb luck that the game doesn't screw you over with it's randomness than it has anything to do with skill.
Overall the game is extremely basic and the only thing you do is fight from one room to the next. The path is as linear as it can get and rooms are largely empty with the minimal amount of items. The combat, weapons and enemies are very basic. There is absolutely nothing to explore outside the main objective. It's also a very short game, there are three fairly short chapters to complete, if you don't play on hard (so don't let my time fool you) where you have to replay the same fight over and over again (mostly the last part). I love the show, and I was actually having fun for the most part with the game, until the last two fights which are just a grind (and it's not just because I'm so bad at the game). Just totally sucked out all the fun at the end.
