Gotta say, quite disapointed this is being abandoned .
I agree, I don't understand why even go to the effort to not complete it. This is an on-going thing with PT for PC. They get uploaded in an unfinished state and/or Konami makes the person take it down before it gets completed. I wish someone would just make the complete PT experience and then upload it. At any rate, this is the best PT version for PC I think that is out right now. Punity and Corridors are the other 2 I have played. They don't have near as much content as this Playable Teaser version has though.
