Sorry but for just $5 I am inclined to trust the original DVloper release on Steam a lot more than this, especially after virus-related comments (although, Avast let them slide as probable false-positives on my PC)...
Plus, if you watch CaseOh's hilarious pair of play-throughs on YouTube, you'll note several differences, particularly the intense musical cues when Granny spots you and chases you ....
