There is no way to get the Android version legitimately, such as from the Google Play Store. You can still re-download the game from Google Play if you bought it before it got taken down by going to your purchase/download history. Episodes can't be downloaded this way. If in doubt, the Cache is the required game files and Episode 1 of both seasons. 



 
Some newer devices don't run the game well (see bottom of page). If you want to play the game, you'll need to download VPhoneOS, which is an Android 7 and 10 virtual machine for Android. After you install the app, the game installation process is basically the same as the one on this section, so you do not need to worry about anything else!

Beware the following when downloading episodes for Season One!!!

Downloading the episodes on PDALife from the Adreno, Tegra or PowerVR dropdown may result in the episodes not being recognized ingame.
Instead, download the episodes from the Mali dropdown.
This should work for all supported CPU sets, regardless of PDALife saying this would work only on Mali.
