You did some interesting things with this game. The ambient background sounds along with the filter effects did a great job of creating an unsettling atmosphere. The story concept was good but the translation took away some of its impact. The enemies are very unforgiving, I would suggest starting off with fewer to let the player get used to knocking them. I think you have a talent for horror games but the gameplay needs a little improvement.
Just found out I played the hard mode version too lol
