I usually don't do well with horror games as a whole, but this definitely created a creepy atmosphere especially with the sound effects. I found it a bit hard to navigate with the limited vision but I guess that is where the flashlight/lantern mechanics come in - although it did feel like your vision is oddly larger without the lantern on. It was definitely helpful to have some of the key interactable highlighted in the dark.
The custom sprites and busts are really well done! And nice touch with the flashback cutscene that introduces some mystery with that creepy bunny. (Gotta find a holy hand grenade and start counting to 3...)
