Well, initially the game is super intriguing. Both the story and the visuals. It left me very intrigued. So much so that I finished it and got the ending (salvation).
But there are a few things I want to point out here.
I've finished thousands of horror games. So I'm kind of hardened to the dark atmosphere and things like that. So, in the mid-game, I confess it got a little boring, because I was sure there wouldn't be any kind of risk in the game. So it was literally just exploring the scenes and reading the documents, but that's okay, the dev wanted to do it that way and I respect that.
Overall, up to the ending (salvation) that I got, it was interesting, even without any scares or risks. The only real problem, in my opinion, was the disappointment of not having any save system to get the other endings; knowing that there are 6 endings and having to start all over again, to go through the same part of walking back and forth, was a bit of a letdown for me. So I was content with just one ending. If there had been a save system, I would have quickly discovered the other endings, as at least 2-3 are in the endgame. And the others are in the middle of the game.
But it was a pleasant experience and I will certainly keep an eye on your other projects. I liked your style and I hope you create more games like this (and please include a save system).
