Hehe holy mother of jumpscares, batman!
The mood of this game is pretty cool, plus the puzzle mechanics. It took me awhile to grasp that I could keep doors closed, but then I started carving my path in a clever way and got to the ending. I had to restart the game as well because I accidentally used the water mug as a key lol.
It's weird. The monster isn't THAT scary looking, but for some reason, I would always jump when I saw it haha. Maybe it was the camera, the sound effect, I don't know, but it seems like you nailed it.
Good job!
