Looking for a way to restore the missing levels in Sheep Happens after the servers went down

Hey everyone,

I'm trying to bring back an old mobile game called Sheep Happens. It was removed from all app stores a long time ago and only runs on older versions of Android.

Finding, installing the APK and running the game is easy enough, and the first world works perfectly. However, the game was originally designed so that Worlds 2 and 3 had to be downloaded from the developer's servers upon reaching certain points. Those servers have been shut down for years, so if you install the APK today, you simply can't progress past World 1 — the game just fails to connect.
If you know anything about it or maybe even own a device with the files, I would be very grateful for any leads or advice!
