constently overwritten values

[Rastakiwi]

Hello. This isn't a request, but I just want to take this game for example: I tried to cheat growcastle's currency (a simple and addictive tower defense game i recommand you by the way). I already succeesed cheating money a long time ago (i think it was with negative price purchase) but not gems.

Now, I can find the currency values, but they are overwritten everytime and I didn't find any encrypted currency value that could be modified. Do you know what could be the cause of this overwriting ? How could I bypass it?

Obviously, if data is written there, then they are taken from somewhere.
Most often they are encrypted somewhere.

Ok thanks, I wasn't sure it was the only case possible ?. (About the game, I'm going to search for encrypted currency value more "deeply", because the game seemed not very protected so I didn't go really deep in my searches)

search for encrypted

Encrypted search of GG work not for all encription. maybe you need general fuzzy search for this.

Yes you were right. In this game, currency (and maybe other values) are encrypted. Values are Qword, and I found that 1 = 2^28; 2= 2*2^28; etc... in the encrypted value, same for diamonds!

Edit: No sorry, this is more complicated, for example, 60 ≠ 60*2^28 although the number can be represented in Qword. I don't really understand the encryption. I also tried signed Dword max value (2 147...) = 8 ; 0=0 ; -1=-1 ; -2=Dword max value, and it look like the encrypted value starts from 0, augment while it is < Dword max value, and then come back to a low value and do the same untill -1, when it finally equals dword max value. Really weird :c
