are there any cheats for this game ?
He spends fookin' years to make the game and you just want to cheat? The hell is wrong with you mate?
There is always a possibility to cheat, even if author didnt added any cheats in game. Just use your mind. If you have "google" and you cant find one very simple way to cheat in any renpy game - then you have no rights to cheat.
I think some cheatcodes are given to Patrons that support the game, would need to check the Patreon description though.
