This game is server sided. I have source code of a previous version.
The version you get from google playstore is obfuscated by proguard.
I would like to share this, as i'm maybe not skilled enough to sort out a pure cheating software for this. ( and also because my computer isnt able to emulate android, make things even harder for testing )
Let me know if you are interessed.
