Try to keep any access points you’ve used hidden from the neighbor, that way you can always make use of them if you have to retreat back to your house.
While this creates additional noise, it will make it less likely that the neighbor will be able to sneak up behind you and catch you. Not only will you come across items you might need at later times, but you’ll also find little secrets that might help you out.
You never know when he might be lurking, just waiting for you to get comfortable. Take your time as you make your way through your neighbor’s house, and always watch your back.Just be careful, as your neighbor constantly learns from your actions, and he’ll often rebuild his defenses to cut off access points that he’s discovered you making use of. Just about every item that you find in the game has a purpose, and learning how to make use of those items will be key to getting into your neighbor’s house without getting caught.
