Such cheat codes are not needed in this game, as they will violate the overall concept of the gameplay and plot. If you are not interested in the story, then it is better to play another game.
Using the free version, which is available on this page, you get a full-fledged game that will not ask you to pay extra for anything. And its difficulty level allows you to complete it without cheat codes: just delve into the plot of the game and, if necessary, use tips from in-game assistants: the bartender, the fortuneteller and the library. As practice shows, cheat codes here are only useful when debugging the game.
