I extracted it but I have no idea how to install it
yeah that's it I have no idea what else to do 😂
Might try renaming the file from a .rar to a .apk? Might give you an install prompt after running the .apk in the RAR app. Seems to work for me on most games, though I haven't downloaded and tested it with this one specifically.
I tried it actually that was the first thing I did when I saw that it was zip file ;p but sadly it doesn't do anything
