Here are some links for you
The whole pricing structure makes it unclear what exactly differs from version to version, or how much you'd save getting the bundle.
Also there's nothing on the Groupees page (not that I saw?) stating clearly if these are "unlocked" versions with no In-App Payments, or partly unlocked to avoid a pay-to-complete/pay-to-win scenario, or if you're just getting the installer for the game as it exists on the Play store.
And there's no indication if your Groupees download has all extra data, or if you'll have to wait ages for your phone to get more files (an annoyance raised in some of the reviews). Hell it doen't even say if the bundled are ad-free!
If anyone can shed light on anything, that would be great.
