That's not my Neighbor
It's 1955, and for unknown reasons, doppelgangers are more common than usual. Therefore, the Department of Doppelganger Detection (D.D.D.) has taken action. You are the doorman of an apartment complex, and you must decide whether to let in those who claim to be your neighbors.

“Spot the difference but with doppelgangers. Another simple and fun game that takes some memory to see if your neighbors are really human.”

“I recommend. The game has no depth, but is fun as a gimmick to play for an afternoon. I paid 2.99 for it, which seems fair.”
“nice game for late nights when you want to play smth but youre too tired for smth that takes effort. cant complain with that price”

“cute game, not too long, can be hard to spot whats wrong, but was fun. can't wait for more”

“Really fun little game with a lot of replay value. It's short, but I imagine you can rack up a fair amount of hours if you're gunning for all the ending and collectibles. There's also an endless mode for if you enjoy…”

“If youre not going for 100% and just wanting to have fun this game is a good game to grab. If you want to complete it to 100% you need to farm for the wanted posters a ton, this is not only tedious but extremely boring…”
“this game is okay, personally the tutorial and intro is too long, but it still is a little fun, its good as a puzzle game its nice :)”

“Rating: 5 / 10 That’s Not My Neighbor starts strong with a fantastic 1950s aesthetic and a creepy, "Papers, Please" style tension. The first time you catch a doppelgänger with an extra eye or a melting face, it’s genuinely satisfying and a bit unsettling. The Good: Art Style:…”
