This application have contains about all guide for playing hello neighbor.
For those just jumping into the game and getting frustrated by the lack of explanation on the game's controls, there are a few basics to keep in mind. You can have up to four items in your inventory at once, with old items you pick up disappearing and going into previous inventory slots. After the opening segment, press and hold E to pick up any object that makes the reticle become a larger circle, then hold the right mouse button to aim and release to throw. The longer you hold, the farther and harder it goes. If you only right click without holding, objects won't actually break windows.
Objects can also knock over the neighbor, so keep something like the bowling ball or even a cup in your inventory for situations where you can't hide. If you hold down the right click for a stronger throw, he'll be knocked off balance for a few seconds so you can get away. Hiding under beds or inside cabinets only works if the neighbor didn't specifically see you enter the room, so you need to get ahead of him when he's chasing you.
