One of the standout mechanics is the sound system - granny's ears are super sharp, and she can hear even the slightest creak of a floorboard. This adds a whole new level of tension to the game, as you've got to be careful not to make a sound while you're sneaking around. You can use this to your advantage, too, by making noise to distract granny while you sneak past her.
The game also has a brilliant puzzle system, with cleverly designed challenges that require you to think creatively. You'll need to use items in unexpected ways, like using a wrench to fix a broken door or a hammer to smash a lock. The puzzles are tricky, but not frustratingly hard, and the sense of satisfaction you get when you solve one is amazing.
