I beat No More Heroes 3. All in all, I'd say that the game felt very uneven. The overworld of the game had more varied environments, justifying the open world better than NMH1, but once again, there wasn't much to do in them. The boss designs were great, and the fights were more varied than your standard hack-and-slash fare (handling the shifts in gameplay much better than NMH2's fight against Charlie MacDonald), but
half of them were bait and switches, if you count Velvet Chair Girl being replaced with Ohma, and the levels before bosses were completely removed for no apparent reason. (aside from Midori Midorikawa, which was probably one of the more memorable parts of the game thanks to that lead-up)
The game had a great sense of humour, but a lot of major story details went unexplained - for example,
Henry went from a calm, collected, humourous foil for Travis to an insane berserker who's completely serious and out to destroy the planet, and his voice actor makes no attempt to sound even close to Quinton Flynn's voice (he doesn't even attempt an Irish accent), and the only explanation that we get is "I watched a movie about God." (there's also Jeane the cat having a completely different voice compared to Travis Strikes Again, and Dr. Naomi inexplicably being a giant tree, but those were goofy enough that I can just accept them) Also, the game basically became a commercial for Daemon X Machina at one point.
The Death Glove powers helped to spice up the combat, but it's a shame that you only get one Beam Katana in the entire game. Maybe I needed to adjust the audio settings, but I don't recall the music being on par with the previous games - there wasn't anything that I can recall which lived up to the heights of
Season of the Samurai,
Mach 13 Elephant Explosion,
We Are Finally Cowboys, or Philistine. Another detail that I noticed is that there were typos in the menus (such as the e-mail tab saying "Turorial" or the objective after you've beaten the game saying "You become the stongest assassin of the universe" - not sure if that last one's an intentional reference to old-school "Congratulations" screens like Ghostbusters on the NES), which seems like a weird oversight.
Overall, I liked the game, but I felt like it had some flaws.
