I suspect that if I was living alone and messes somehow got inexplicably cleaned up and such, that would scare me even if I didn't actually see the ghost itself. (But maybe this old woman is different than me in that respect.)
I liked this game.
One minor issue: The thought balloon that appears at the beginning goes away on its own, which is just barely enough time to read it. But also if I win and click Retry, then the text in the thought balloon doesn't appear and the game just freezes.
