Trying to Rip from APK

I extracted the contents of the apk file with WinRAR, then extracted the game's texture files with Unity Assets Bundle Extractor. The files are in the "assets" folder. Specifically, seleting "globalgamemanagers" or "MainData" (depending on the game) will give access to all of the game's files (assuming none are kept in an external location, usually happens with online-only games).
