Omori is a intriguing game that made me arrange theories and change them almost every time I got a new piece of lore. The people that recommended me really, REALLY enjoyed this game so I did 100% of the good ending run taking 70h(which you can get about 70%ish of the achievements on Steam) to see what it was about, though, I wouldn't recommend playing as I did for your first run. Just before you all jump me let me explain why first.:
If you plan on doing most of the achievements/quests/exploring in the game, this will take a while. Omori has a lot of side quests that you can do, which is a double-edged sword in my opinion. While you have a lot of replayability and world development, it can get tedious quite quickly and distract you from the lore (you could argue that (((spoilers))) sunny is trying to distract himself from all the trauma, therefore, making the headspace like this, but again, I don't think you should discard gameplay for the sake of the storyline).
In conclusion, I have some critics when it comes to general gameplay, BUT please don't let that divert your attention from the fact that Omori is a wonderful game with an amazing story, music and an engaging battle system. If you ever get a chance to play it please try it, the game is not that long if you focus on the main story, and it is most definitely a must play game.

DAMN, eu esqueci de dar log nisso aqui, né? bem, tinha uma época que eu era o maior meatrider dessa merda, era meu jogo favorito e eu investi praticamente uma vida no 100% disso. hoje em dia? o jogo é bem meh, na real. a gameplay é bem básica, com um passe entre personagens e aquele medidor que eu não sei o nome adicionados que deixam o jogo mais único, mas ainda genérico. o tag entre personagens fora das batalhas provavelmente é inútil de propósito (eu acho), as side quests são muito nada haver e pau no cu da maioria das conquistas. a história tenta ser muito edgy e a fanbase é um SACO DE MERDA DE TÃO HORRÍVEL. eu te odeio, goularte. soundtrack bangs tho.

I cried with this game? Yeah, but it was not for me, I loved the combat, almost entering that zone when you are playing RPG games when you just think and act and it feels good, but the story was not that great as people say it is, I think that the whole Mari and Sunny thing was not the way to do it, unrealistic and just... Edgey, I prefer not to play it again, I finished it start to end at the release for the nintendo switch, fucking 12 hours, and after doing it I just chilled at the morning, what a weird day that was
