I used VPhoneGaga emulator to install the game, then I used GG outside of the emulator (real phone) and attached it to the game. Search for the game process on the list of VPhoneGaga processes, it should look like "VPhoneGaga(titan**_***:com.hidea.cat)". Look for the one with the largest memory usage.
After attaching there should be no issues. You can start searching for the values of Gold (FLOAT), Energy(FLOAT)and Gems(DWORD) and the memory range is "Anonymous". These values are a few addresses apart from each other so it'll be easy to look for them. These values are not server sided so editing them normally should work.
