I could write a novel about this but I'm going to summarize it into a few paragraphs. This game is nerve-wracking, sinister, uncomfortable, very intense and many other things - all aspects that should make up a horror game. The atmosphere is very ominous and I can tell you are a Silent Hill fan (much respect), yet original at the same time. I know what the full backstory of the game is now and it is captivating.
However, what strikes me most about this game is the look of punisher's character model and design - he honestly puts any horror character I've seen to shame in terms of scare factor, an absolute monstrosity to gaze upon and he is what terrified me above all. There was nothing worse than not knowing where he was at certain points and then hearing those footsteps! The fact he is mute as well fitted perfectly and added to the terror.
The music fits excellently as well, reminded me of a nigh heart attack that the character would have when becoming aware of what was chasing him. It seamlessly worked while being hunted by what seemed to be the epitome of evil incarnate.
Me and my friend consider this one of the scariest horror games we've every played. I only wish it were longer and had more things to do/explore but nevertheless, Kudos Matt , I certainly look forward to seeing and playing more of your work :)
