Nice concept with playing a game while being stalked by a monster. I has a hard time figuring out at first how to sit on the couch, and then I realized you need to look at the TV and then press E. I was looking at the controller directly at first.
My two suggestions would be to add more fake outs with the monster. For example, wind blowing opens up the windows but in reality there's nothing there. Also making the guy in the game move faster would also be nice.
