"Hello Neighbor" is a stealth horror game developed by Dynamic Pixels where you aim to uncover the secrets of your mysterious and suspicious neighbor. Here's a guide on how to play: Act 1: Your main objective in Act 1 is to obtain the red key to open the door to the mysterious location. After a short cutscene, you'll find yourself opposite your neighbor's house. Go inside your own house first. Then, in the purple room, grab the gold key sitting next to the door and unlock it for easier access in the future. Look for a keyring on the wall to your right and take the red key. This key will allow you to open the trunk to the red car back down on the lawn. After getting the key, go back out the window in the bedroom and head down to the car. Remember, the game is all about stealth and strategy. Avoid getting caught by the neighbor as you explore his house and try to uncover his secrets.
