Can't say I would have a good opinion on the game, mostly cause I have a Meh opinion when it comes to the Backrooms themselves and dozens of games that been made on the setting.
Oh yes I did play, even saw the model of Terrifier not sure why he is in the game. For what it is I think its okay, but again I'm not a fan of the Backrooms and this style of gameplay so really take my opinion with a massive grain of salt.
