it's a shorter version of P.T. and the guy who did it nailed the parts he created Unfinished and the guy wants to finish it then release it for Linux\Mac later here's a gameplay footage of the Demo i recorded DL Link http://jedlondo.itch.io/punity
Is it as scary as the PS4 PT demo? I let a Demon into my house by accident playing that demo! Took a few days to clear it out so I could sleep peacefully again.
