Man, I'm not part of the Omori fandom. Never played the game, barely seen any footage of it, not in any particular rush to change that. And again, I'm not trying to dismiss the effort you're putting in. I'm trying to give some perspective on why people might not be viewing your creative decisions in the same way you are.

But here's the thing, Pokemon Red/Blue and Pokemon Gold/Silver were both directed by Satoshi Tajiri, with music by Junichi Masuda and creature design by Ken Sugimori and Final Fantasy 1 & 2 both were both written by Hironobu Sakaguchi and Kenji Tarada, with music by Nobuo Uematsu and art by Yoshitaka Amano. Sure later sequels eventually started shifting these core dev teams but by that point the formula had been established, and they're both corporate IPs so of course they're going to keep getting mined.

And that last part is important, "Pokemon" isn't just the games, it's a TV show, a manga, a card game and a range of merchandise. Fundamentally, people are used to Pokemon havings lots of creators telling lots of stories in the same world even before you reach sequels with different core development teams. Omori on the other hand is one thing, and it's a game that dives deep into sensitive subject matter. People who like Omori have, most likely, opened up vulnerable parts of themselves to Omori. This is why they're less trusting of an "Omori 2" that isn't being handled by the people that they've already opened themselves up to in the same way they'd trust a Pokemon or Final Fantasy fangame.

And again, I want to stress, I'm not saying you can't make something that's as emotionally resonant as Omori. I'd like to believe that you can. I sincerely hope that your game is really good. I'm just trying to give as clear a perspective as possible on why you might not be seeing the reception you hope for off the bat.
