loved the tone of the game. the music and the graphics. I had problems with bugs, I got stuck. but mostly I think it needs better directing.
pictures should not be different in size, moving the shadows would be nice(its definitely a lot of work) so the game wont feel so static, and instead of using giant arrow buttons to move around and open doors, I think you should use a custom mouse, that change into an icon of opened door when you move the mouse over a door... etc.
but even with all these flows you almost creeped me out, good job.
and one last minor thing, when I replayed the game, ending music got mixed with game music, but weirdly it was good, it didnt ruin the experience !
