that might be hard because i do not know what exactly changed. the engine that I use to create the game got an update, and i am not skilled enough to revert the changes
Sorry to hear. Unfortunately I'm not technical enough to help you there. If you ever want to change engine: Ren'Py supports Windows, Linux and presumably Apple. Anyway, thanks for your quick reply!
thank you. Shadow over Blackmore, my other game, is already made in RenPy. Simply changing the engine is not possible without a tremendous amount of work
