If you want something like a visual novel, RenPy is pretty user friendly. Something like GoDot or Game Maker or even RPG Maker could also work. But also, programming can be hard work. Something that would be game adjacent is to make something like a choose your own adventure book/pdf. Could also add in sections where you make a choice and say "Roll a d20. If you get 15 or above, go to page X, otherwise go to page Y". World is ultimately your oyster.
I am a writer kind of person, so writing is the easiest thing for me to do. If you have programming experience, you might like godot. RPG Maker and Game Maker Studio have some easier code and some drag and drop options iirc, but doing that stuff makes the game run worse. This is only an issue for large games though.
Be mindful of what you can do in the time period, and play into your strengths. I've subscribed to this topic so if you want any more advice, I am happy to offer it.
