Hello Neighbor is a first-person stealth adventure set on a sunny little street where one house just feels wrong. You start on the sidewalk, a police officer walks his beat, and the stone house with the blue roof sits behind a white fence waiting for you to snoop. A task journal gives you one small goal at a time, starting with opening the gate into the neighbor's yard and saying hello to Mr. Cao the vendor, and each finished job leads you closer to whatever is hidden inside. The big rule is sound: sprinting makes your footsteps loud, an ear icon flashes, and the neighbor comes looking, so the fun is in creeping, hiding behind fences and timing your moves. If sneaking past someone scary is your thing, try escaping the house in Granny or pulling pranks in Scary Teacher 3D.
Move with W, A, S, D and look around with the mouse. Press E to grab items or open gates and doors, Q to drop what you carry and R to throw it, which is great for making noise somewhere else as a distraction. C crouches, Space jumps, Tab opens the task list, and holding Shift frees the cursor so you can click the buttons on screen. Walk instead of running near the house, scout the yard on your first try before going for a door, and keep an eye on the minimap in the corner so you always know which side of the building you are on. When you come back later, press Continue on the main menu to keep your progress.
