This is pretty awesome, although not what I expected. This is a rogue-like dungeon crawler. I was hoping for something a bit more fixed camera/puzzle/terrible voice acting oriented.
That being said, you did a GREAT job with what you did. The controls are fairly intuitive, you have nailed the look and atmosphere, if not the mood of the game you are paying homage to. The player is a bit OP, and seems to be able to kill everything that gets in her way, which defangs the horror somewhat, but all of the elements are there, and the game loop is classic and well implemented.
If this is your first effort, this is an excellent way to go. You can definitely work your way up to creating something more ambitious. Keep going!
