Omori (mild spoilers for the game ahead)
I've nearly completed Omori. I've enjoyed the nostalgic style of the game and the horror elements a lot, and the gameplay is pretty fun too - but it's the story that's the important part. It's a game about a boy trying to reconcile his dream self and reality. He's spent years mentally hiding from a traumatic event, and the game leads you to confront it and ask if you can find forgiveness.
I think the twist is over dramatic (more akin to something that would happen in a crime drama then real life), but the reveal for the viewer is very effective, and the way it recontextualises other parts of the game and makes things more horrifying in retrospect is super well done. Playing the game in the evenings definitely gave me a creeping feeling I haven't had since I used to read creepypasta at night as a teenager.
The central theme of forgiving yourself and forgiveness in general is very moving. It's interesting that the central act is something it's debatable you could forgive someone for - people will have different opinions on this, so it puts you in the main characters mind as they struggle to forgive themselves.
Although the game is dark and harrowing (there's certainly parts I wouldn't suggest someone who is deeply depressed or suicidal should play), the "good" ending is reached through forgiveness or at least believing in the possibility of forgiveness, and beginning to find your way out of something that felt unimaginably bleak and impossible to handle.
While the story is dramatic, that feeling was something really relatable to me as someone who was very depressed last year and was also involved in causing an accident I felt really guilty about... so while the game might be too unsettling for me to play again, especially with the reveal, it's been running through my mind since I finished.
