Cool little game. I liked going from room to room and figuring out what I could possess. Good audio design. There is some strategy to being in the right place at the right time, watching the human behavior patterns, etc.
Note that the game runs really tiny. I couldn't read the prompts or tell what most of the objects were until I possessed them and heard the sound effects. The ideal resolution would be at least twice as big as the current resolution (but not so big that we can't see the whole screen without scrolling).
