Actually, if you search the App Store for “not my neighbor” or similar terms you’ll find that many different copies of this game are being sold under slightly different names. A surprising number of them.
Edit: Wow, interestingly they are literally doppelgängers with e.g, some of them using slightly different art assets. Is this some meta joke marketing scheme I’m misunderstanding? They still reference the DDD and remind you that it’s February 1955 in the tutorial etc.
