Maybe 1,5* because the idea was nice, but ... nye.
I got intrigued by the cover, because it looks really good. And the idea of a weird mushroom growth all over a city, was nice too.
But sadly that's just it.
The author keeps repeating, repeating and repeating stuff, it got so damn annoying, especially bcs it's a short story. In the first 26 pages, the FMC repeats over 10 times, that she needs to get her father out of the overgrown city.
And the same amount she asks herself, if the fungus is maybe toxic and if she get's sick. Does she get a mask? No, she doesn't. An NPC needs to give her one, then the author conveniently forgets that they wearing masks, or the spores would go through the mask - which is BS. The NPC especially used those "WW2"-Mask Types, that has two filters - fungus spores are way to big to get through them, but ok.
And later they just took the mask off again .. like why bother then.
So yeah, there is a shitton of repeating information, probably to fill the pages. The plottwist at the end was a bit lackluster, even tho the monster description wasn't that bad, but still ... and the fmc was just stupid. Especially bcs she is supposed to be a bigass demonoligst worldwide known, blablabla. And then she thinks "Oh we're three, the monster is one, we get that." ???? She should know that they COULDNT get that, because she knows the monster...
Not a bad idea, but bad realization.
