something i'm curious about

Is there something that we can increase our in-game money and stamina and the level and character level of things like that, from the game's own files or by doing something else.

And I want to add one more thing, I wrote that I downloaded the game from their site, I think it was written automatically, I think I will come to my question again, I cannot download the game from their site and I always encounter problems in other current versions, I wonder if someone can help me in a way that I can download the game with separate server and game files. ? Due to these issues, I will be playing the game almost as it was when it first came out.
