The art and atmosphere was great, though I played through it twice cause I wasn't sure if it was supposed to be a time loop or something >.<
Hard to critique gameplay for an atmospheric horror game, so my only critique is that the art was kind of static. And I know firsthand how hard it is to animate on a short time budget--I just mean that some more layering/parallax in the backgrounds or lights flickering would have been nice additions to the atmosphere, some more dynamic graphics code work would make that beautiful spritework really pop.
Can't wait to see what you have in mind for the ending. Good job!
