I wanted to try the game after hearing word spread about it. I've played other disturbing games, even ones with sexual themes so I knew this would not shake me. And I was right.
I will give the creators this, that they tried some interesting things here: shooting in black and white, no music, fun FMV cut aways. That is about as far as my compliments go though. To me, this game is shock value with the depth of a puddle. It relies way too much on shocking the player by making them perform actions they can't choose against. It's not horrifying if the only choice is to play or shut the game down. True horror comes when you confront a player about what they choose to do willingly on their own.
Commentary on the church, sexual morals, and how people can twist their own perversions to lash out at others is nothing new these days and nothing new was said here. Honestly, it may have been more taboo if they were left to being actual horses you abused. I would advise for their next game to step back from such blatant shock value on work on true horror.
