I'm not really much of a coder, but I can say from my own experiences.What i've found trying to penetration test this game. Trying to change any values with cheat engine or any other of the like only results in sanitization, disconnecting and resetting two cloud default, which I guess is what the one guy was doing by changing his google play stored data instead of the game data, i'm i'm in the process of getting at decompiled data. But if you do active memory dumps on the scripts, you can get a decent amount of the decompiled data straight from the server. If you do it well, you run the game. But they're still obfuscation so it's not perfect
The only main loophole I've really found. So far, but I don't have the technical knowledge to do a whole lot. With this loophole is I found a way to bypass the sanitization, on the chat level. By using <scr<m>ipt> you can inject html code into the chat window. Like "<a h<m>ref="exit"><co<m>lor=red>[EXIT]</co<m>lor></a<m>>" I just need to find the specific calls and tags and I bet I could make it function as a script/dll injection method.
