This is really nice! The graphics especially are top-notch. My only real criticism is that it's a bit easy. I think it would have been really cool to have ghosts that moved a bit more quickly, so you were forced to balance between looking forward and seeing where you're going and keeping the ghosts stunned. As-is, the ghosts are basically never a threat. I also think some good dungeon-ey music would have improved the overall ambiance a LOT. That said, this is a really cool idea and definitely is worth exploring/expanding a bit!
