Put a warning, because this game is very story driven.
If you choose to do a “genocide” run of this game (yes, that’s what it’s called), there’re alot of differences to the other playstyles. They are interesting, but what struck me the most are the substantially more difficult bossfights. There are only two of those, so I decided to show these off. They also kind of resemble the touhou play-style with lot’s of dodging and trickery. The first fight is is Undyne (the Undying), the easier, but none the less still very interesting fight, with lots of progression in the fight-schemes itself. There’s just a few patterns which repeat. As of rewatching this I notice the trumpets in the song sound pretty much like those in touhou. Coincidence?
