The good:
-Enjoyable turn based combat, even for me, a turn based combat hater
-The story is super engaging and kept me interested and succeeded in making me rather see the real life segments in the Sunny route and the headspace segments in the Omori route despite both having 90% of the same headspace content.
-The way it represents the real depths of depression are super relatable and well done.
-The characters are really good and the interplay between headspace and their real world characterization is great.
-A lot of the scares are good and don't exclusively or even regularly rely on jumpscares.
-The console exclusive Basil Boss Rush is really good, don't skip it if you're generally not a fan of boss rushes.
-excellent soundtrack

The bad:
-I think the twist is too extreme and stretches the believability of the other friends forgiving Sunny and Basil. I think having them simply make it look like Mari fell on her own may have worked better.
-Humphrey
-The Abyss
-There absolutely should have been a scene in the hospital room at the end of the good route. Part of the reason Sunny is willing to start to forgive himself is because he thinks his friends will end up forgiving him, their words are integral to the final confrontation with Omori. Maybe the writers thought that Sunny's belief he'd be forgiven was enough to assure the audience, and maybe it is for some, but not for me.

Overall the game is excellent, despite a few, what I view as major flaws.
