If you are good with visuals, you can use chronicler which is a visual choice script editor.
Write up at least the first chapter/ intro before you post or game idea or consolidate all your game ideas into one thread so the forum is less cluttered. I think a mod can consolidate all your threads into one. There is no rule against working on multiple games at once, but there should be more than just the concept. I still highly recommend not to unnecessary gender lock the MC.
