There's probably some way to do it, but the Android version is relatively new and I don't think there's been a lot of research on how to decode and edit its pers2.dat file. It's possible that it's similar to the iPad, but either way you'd have to decode it into an editable file.

Even once that's done, you'd have to be able to edit the file properly to show that your levels have been completed. I'm very inexperienced with this, but there's information on the file's format and syntax here, if you're interested. However, unless you can remember, your best number of balls collected and moves taken wouldn't be the same as previously.

Well, iOS versions have a plist file meaning it's not encrypted. Considering android phones are also mobile device, my guess is the save file won't be encrypted, though it won't necessarily be called pers2. The folder organisation should be more or less the same as PC.

If it is encrypted, I expect it uses the AES method.

Why would it ne encrypted if no one is supposed to access it in the first place!

I dunno, but the Windows/Mac/Linux ones are. But Soultaker cracked it.

So that nobody can access it. And maybe for the game to read/write it more easily.

Well, I inform you that iOS has no encryption.
