I know nothing about making game but honestly i want to make one of my own currently im learning using AI to help me and online tutorial but still very hard to make a game have any body try to make a game like this how do we go up or down in a cave in a 2D game like this can anyone help me on this journey?

Do you have any programming experience? What have you tried so far? Honestly I'd discourage using AI for anything other than maybe explaining code, but even then you should go to the documantation first. You won't learn anything from just copy-pasting code, from AI or from tutorials. (I'm also not sure how accurate AI-generated code for Godot even is... I only tried two or three times and it gave me total nonsense with made up functions and libraries that don't exist.)

If you have no previous game dev experience you should try making a couple tutorial projects before you try to make something more complex. I personally haven't read it but here's one I just saw on the forum's front page, and I'm sure there's plenty of free tutorials out there :-)

Edit: BTW... Most people have cool ambitious game ideas but either never make them, or make them after years of working on smaller games. You'll learn faster (and be less frustrated...) by creating a lot of smaller simpler projects rather than trying to make your dream project right away :-) But do what you want of course.

    housatic thank you for your advices honestly im learning bit by bit and AI does helped out alot though

        JasonLy28 Of course as long as you're using it to learn and not just to have it do all the work for you, it's fine :-) Good luck
