It's going to hurt for me to give it a thumbs down but the game is just kind of silly.

Don't get me wrong, the game is surprisingly a whole lot more polished than most other indie horror games you can find on Steam, it's well-crafted and doesn't have bugs or glitches-- at least in my own playthrough.
It wasn't infuriating to play nor does it overstay its welcome, but a lot of the game just has a lot of design choices that just makes you think it's one silly game.

It's not a big part of the game, but it kind of ruins the immersion a little bit when you just see anime posters plastered around, it's a little goofy-- but charming in a way that I feel this game is best taken lightly to just goof around in it.
Then you see like blank sheets of papers that are apparently readable letters, then you see a paper that is quite literally just a map-- but no, that's also a readable paper. Oh look here, a paper full of Chinese writing but, oh, none of what it says in Chinese is what it says on the readable letter.

The font, while I do understand why: Blusagi Team is the name of the Developer, I just think it's a little silly for a game that's supposedly horror.
A lot of the game's pacing is back and forth slow walking for the sake of cheap jumpscares that can get a little annoying.
The plot of the game feels like it takes a lot of inspiration from Fatal Frame Maiden of Blackwater, but that's mostly speculation with the concept it tries to go with.
The rain filter can get a little annoying and just makes it hard to see anything, especially when during the moments you'd need a flashlight, you don't have one but during a time you don't need it whatsoever, they give you one.
The letters scattered around the map for lore does indeed serve a purpose for its world-building, but a lot of it can already be speculated and understood from the start and many of the ones you find later one are nothing more than just confirming what you pretty much know or repeating some parts of the world they're building it making it pretty obsolete.

I do admit that the game has had some few good scares that made me jump and uneasy at some point, but overall it just comes off as a really funny, silly game.
I would say that this game is lovely and charming in a way that it's so goofy and ridiculous, but I do believe in a horror aspect especially its quality/immersion-- if you're actually looking for a good horror game, this may not be it.

Stuck out in the rain looking for your keys is not a strong foundation to build tension on for a horror game to pay off.
