I want to preface this by saying that I still think Omori is a great game, but because of its presentation, narrative focus and obvious Earthbound inspirations it will always inevitably be compared to Undertale, which is of course an absolute masterpiece in cohesion and narrative tightness.

This was also main criticism of it, that it tries to both do this emotionally very intense narrative but also a full-on JRPG with all the progression and bossfights and what have you. For me, who went in looking for something similar to Undertale, I genuinely felt like there was "too much gameplay". I think the combat system was actually quite good, I just wasn't particularly interested in it because I wanted to see the story. Similarly, a lot of the story almost feels like a distraction, I'm sure there's some underlying connections between the different places you visit but when I played through them they didn't seem particularly relevant at all.
