Doki Doki Salvation is a Doki Doki Literature Club mod where MC decides to check on Sayori the night before the festival, and walks in on her about to hang herself. He talks her out of it. The mod revolves around MC helping all the girls deal with their various problems... except Monika. Monika has lost her ability to tamper with the game and is not happy about it.

The mod is mostly linear, and focuses on Sayori, but it's fair to all the girls. It ends with Monika confessing to everyone, and a really believeable and emotional scene around it. Assuming you choose to forgive Monika, the game delivers the happy ending it promised.

Also, slight content warning: there is some (arguably justified) nudity in this mod, as well a sex scene. It doesn't show anything lewd though, just makes it clear what's about to happen and then cuts to the next morning.

The mod is definitely good. Despite that, I have two major criticisms, both moral/philosophical:

It's also worth mentioning that the way the story punishes you if you don't forgive Monika is really, really stupid. It is totally unbelievable that Natsuki and Yuri left the club. That experience would have strengthened the bond between the club members enormously, but the writers just wanted to drop the anvil that not forgiving Monika is BAD, so they made the story bend over backwards and completely shatter to show you that. It's honestly the worst example of a shoehorned moral I've ever seen. In fairness, not forgiving Monika in that situation is a totally wrong and indefensible choice, so whatever. It's not that big a deal if the story breaks to push a true moral and it's only if you choose the evil ending.
