May I please ask you about how did you extract the assets?
I've tried every known method on cracking the il2cpp unity game on youtube and nothing have worked. I'm not sure if I can write the utilities I've used to try and hack the game, but TLDR nothing have worked. Do you mind telling me how to do that?
That game seems unbeatable somehow
I think the "AssetRipper" was used for that. You need to launch it and select the "File>Open Folder". Then you need to select the game folder, and then select "Export>Export All Files". Select the separate folder and click "Export Primary Content".
For FutakinValley most of the IMG assets will be in the "Assets>Texture2D"
I'm not very good with that, maybe others have better solution but it works for me.
Sorry, I have no info on how to hack the game, but it's demo anyway
