There are these weird surprises that'll keep you on your toes - like, have you ever been playing along, thinking you're safe, and then grandma just pops out of nowhere? It's hilarious and terrifying at the same time. And the cool challenges - like trying to sneak past grandma while she's sleeping - are so much fun.
The little details in the game are what make it so immersive - like the creaky floorboards and the way the doors squeak when you open them. It's so easy to get lost in the game and forget about time.
