I haven't played any Amita Design games before so I can't really compare this to their other games.
This is fine. There were moment when I was engaged and moments when I was bored.
Overall, the narrative is pretty disjoint and abstract. Maybe a lit major would have fun piecing this together, but for everyone else, I'm not sure.
For the main character, the mood is a constant shift of up and down between happiness & relief and horror, without much rhyme or reason that I could discern. I personally tend to dislike it when they overuse that particular trope in horror
I wasn't particularly scared and I'm far from scare-proof. A couple of scenes made me laugh and if you have a dark sense of humor like me, you might get a kick at some of them. I enjoyed the scenes with the rabbits a lot so if you're on edge at the beginning as to whether you like the game or not (like I was), wait for the first rabbit scene and then you'll know. It shouldn't take too long.
The puzzles are adequate. There are some puzzle require that you capitalize on momentum which was a newish interesting experience for me in the context of a puzzle mouse-driven game.
And of course, the visuals of the game are very interesting. They often feel like a painting. In that regard, the game is very solid and consistent through and through.
So overall, a nice imaginative artsy game that has some highs and some flats.
I don't consider it very scary though it might tickle your funny bone if it is dark.
Also, unless you enjoy doing significant mental gymnastics to piece together things that don't make much sense, don't expect a coherent arching narrative between the puzzles. You might be happier if you consider the different puzzles to be standalone short stories with the same main character.
