Here are some of my opinions based on my experience playing this game:
Mouse moves kind of fast, maybe you should add a mouse speed option in the pause menu?
I love the style of the abandonded house taking place in the pitch-black night. I also like how the theme stays consistant throughout the whole game.
The game really does a great job giving the player the sense of dread, especially with a blood trail leading to an unknown horror, and the long dark hallway that gets darker the farther down you travel. I was really preparing for some sort of jumpscare as I was going down those paths.
I was really hooked on the story aspect, along with the feeling of solving a mystery of what this place is, who is this woman, and what happened to this woman?
I was kind of hoping for another puzzle in the second rewinding section instead of just picking up a tool and being done, especially with how cleverly designed the first puzzle was. Perhaps you could have done something where you need to get an assortment of tools in a certain order to open the broken door (with a plot twist of it being the order of tools used to torture and kill the woman)?
This might be kind of a nit-pick, but I'm not sure if I was a fan of the sparks effect of the time traveling objects. The game has a dark horror theme to it with grimey and rusted objects everywhere, and the bright cartoonish sparks kind of takes away from the immersion a bit. Perhaps something like a red and black smoke-like aura coming off of the objects would be more fitting for a dark environment?
I'm hoping you can expand upon this story in the future. It's not too often that you get to see a mystery-horror game that doesn't consist of cheap jumpscares.
