Have you tried cheating this game? What happened?:I have tried every value format in GG from Dword to xor but no nothing works 

I have tried to modify the values directly but it doesn't work after a few times I found the specific values but even when I modify them they get back to the normal state then I decided to modify the price of stuff in the shop guess what nothing happens
Comments: I'm not a big fan of this game but I want to know how to hack it with GG i like how they protect the values and make it so hard to hack at least for me but who knows maybe you guys could try your methods on it I will appreciate your help 

but please no mods
