: Extreme compression can lead to missing textures, broken AI (the Neighbor's learning behavior), or files that fail to extract correctly. No Updates
Have you successfully installed Hello Neighbor on Windows 7 using a compressed file? Share your experience and file size results in the comments below (but remember, no direct piracy links).
