13049 Thats Not My Blocky Neighbor Updated: 2024-04-11
Thats Not My Blocky Neighbor

It's 1955, and the world is ensnared in a bizarre mystery: doppelgangers are appearing at an alarming rate, causing chaos and confusion. The D.D.D. is on the forefront of this crisis, striving to maintain order and safety. 🚪👥 Your job is a simple one: Allow or deny the request of personnels seeking entry into the building. But be careful, my friend! You must stay alert and pay attention to every single detail, or else you may fall victim to the doppelgangers, too. This game draws inspiration from Nacho Sama’s gripping "That’s not my Neighbor". Please support the creator by playing the original. 🎮💖 🚨 DISCLAIMER: Venture into this shadowy world with caution - elements of light horror and blood may not be suitable for all audiences. Player discretion is advised! 🚨 Tags: ThatsNotMyNeighbor, That'sNotMyNeighbor, That'snotmy, thatsnotmy, Horror, Clone, Neighbor
