This one was pretty solid. Good job. I like the choice of big spaces or small spaces. I think the best part of the game is the grungy texture work, the textures really sell the setting for me. Nicely done, my friend! The map is a cool concept and the game feels pretty challenging and anxiety inducing... just how I like them!
I think for the flashlight, you should consider adding a small-faintly lit OmniLight3D so the flashlight itself can slightly be seen and the walls can be seen when you are close. Might make the lighting system pop a little more!
