Girls Knights Squad - does GG work for this game?

[pglyn]

hello guys, i was wondering if this game (Girls Knights: SQUAD RPG - https://play.google.com/store/apps/details?id=com.gamepub.cc.g&hl=en-US) is compatible with GG? 

for context, in another game of the same devs (Merge Girls: Idle RPG - https://play.google.com/store/apps/details?id=com.gamepub.hab.g&hl=en-US), the values on the premium shop of this game is changeable with GG, the way it works is finding the value (price of the purchasable pack, in korean currency, WON) under DWORD, then changing it to 0, making it free. heres a YT video demonstration of it: 

 

 

now in their newer game (girls knights), there is a pack with the same price (109000), found it under DWORD, but when i try changing them to 0, the game just freezes.

i tried hiding GG from the game, i tried running the game w/o protection, i tried changing the values one by one instead of all at once, setting prevent unload to lvl 3, but the game still freezes after i changed the 109000 to 0

can anyone help me with this? or is this game unhackable with GG? thanks in advance
