Cool game. Good idea and a lot of fun. :)
I just had one problem: I sometimes have a hand of poltergeists but no furniture to possess. And since I have a small deck, if I pull a new hand, then I have a lot of furniture, but no poltergeists to possess them. ^^'
Since is easy to reset and the levels has little waves, it's not a big problem, but a possible solution would be to ensure that you have at least one of each card in each draw or else to be possible to possess the furnitures already in the room.
