Nice job on your first game. As a couple of others have said the default mouse sensitivity was much too high but I was able to figure out turn it down. I like the idea of using the light to reveal things but also having to manage your energy for it. I thought that the can for the health was a battery at first so was a bit confused with that. It would have been nice to have some identifying features along the walls or floors to help the player figure out if they've been somewhere already or not. Definitely a good spooky atmosphere and pretty cool that you included different difficulties. Nice job overall.
