I love That's Not My Neighbor, it is such a simple yet fun game, the doppelgangers are sometimes horrifying and the milkman is always hot. The Campaign Mode is also such a good update! Some of the endings are really difficult to get, but every time I play it, it's always a new experience with some random new doppelganger that makes me go "huh, wtf is this supposed to be now?!"
I played through the entire Campaign Mode and got All 5 Endings. Here's the full gameplay, edited down into a short video! Hope you enjoy or at least find this video useful in completing all your endings ^-^
