One of the coolest things about Granny 1 is the escape mechanism. You'll need to use items like the wrench to fix doors, windows, and other objects to create a way out. It's so satisfying to finally escape, but be warned: Granny will get harder to evade as you progress!
The sound design is also worth mentioning - the creepy noises and Granny's terrifying vocalizations will have you jumping out of your seat! The atmosphere is tense and foreboding, making every step feel like a risk. You'll be on high alert, waiting for Granny to pounce!
