A pretty basic horror game. The graphics are good for a pixel game and it controls well. I found a major problem/annoyance being the lack of checkpoints. Because the maps are not randomized once you figure out one level, you are forced to redo it every time you die making for a very annoying, grab the key go to the exit, hope you don't die scenario over and over.
Something you should add is rooms instead of just dead ends, adding tables and chairs, pictures and paintings will help make it feel more alive then just a massive hallway. Another suggestion is changing the wall/floor/ceiling textures between each floor. Adding paintings to the hallways will make it feel more unique then just gray hallway everywhere.
