I'm so easily spooked and I definitely felt tense with the music, atmosphere, and how the camera only lets you see one room at a time haha. That said, I wish the monster can be a bit more predictable, as I hid from it once and when I came out I couldn't find it anywhere. Maybe it's a design choice that it works this way? But it felt like the monster popped in and out and I couldn't predict when to hide.
That said, the art is wonderful! The limited palette is moody and a great choice!
