Most times I see this it's because of total file size and what it is being installed on. If it was an all in one download it screws up the installs on many people. Think of it- up to 0.14 is 2 gigs... 0.15 to 0.22 is already 2 gigs. Now that's for PC. Try shoehorning that in to an android. For an awesome free game don't ya think it's worth a little file shuffle?
