I'd say learning to code, but that isn't always necessary.
Bitsy is a great tool for creating unique narrative driven games and it's found right here on itch.
Otherwise, you could try taking very slow steps and gradually learn to code in any C type languages since that's an industry standard. Unless you want to make games for the commadore or vic-20 (which I doubt), picking a language like C or any other Object-Oriented Programming language or OOP language should work.
Try and take it easy. Best of luck n all that.
