I really liked this short, but atmospheric game! I like the artstyle, and the overall feel.
However, the game is scary only for the first minute, and I think there's some reasons for that. I would DEFINITELY recommend to later on add footsteps to the enemy, and overall more sound cues around the player. Trust me, sound is really important in a horror game.
Also I agree with others, the flashlight should be brighter, or maybe should have a longer radius.
But I respect you for even finishing this with your cat passing away. I know the feeling, It's difficult. Skye would've appreciated you putting em in your game :)
So great job, you should definitely update and fix the game up!
