I don't know what I'm doing wrong but every time I download the Android version and extract the file for the apk only has 75 mb am I doing something wrong?
Yes, the apk is 75 MB, but there is also a game folder containing the game data that needs to be placed in the correct location. This is explained on the game download page and when you launch the game. A step-by-step guide is available in the archive (pdf file) or here.
