Soul Tax is a game about ghosts. And haunting people then killing them in various different ways. It's a sharp little number, with some solid writing and a cool aesthetic.
It's a cool idea, and really gives you a certain amount of freedom with regards to how you dispose of your victims - and it's always fun to possess some poor bugger then throw him out the window.
Soul Tax is a solid, fun game and I reckon you should play it.
