there is a file called variable.gd which is the file that holds most of the game mechanics, you can change your earnings and reputation easily by changing it to any number you want. You can also increase the atk and matk damage higher so that you can defeat the enemies more easily, you can even change the upgrade limit factor to zero which means free factor increase and etc. These are files that can make your gameplay easier or harder it's your choice
located in attempt-conquest\src\core then change variable.gd to txt (after you are done editing the file change it back to variable.gd)
