the monsters really scared me, they remind me of sleep paralysis demons. the colors are great too, i like how strong the ambient lighting is. i think turning down the smoothness on the materials would tie things together more because unity adds the white specular highlights by default on the urp lit material. aside from that i like the look of the shotgun but the particles make me think the gun has spread so i was actually missing my shots for a while until i figured out it was raycast. doing 4 more raycasts in a cone shape would help to sell your shotgun effect and make it so you could shoot multiple enemies at a time. overall i had fun, good job!
