i'm trying to figure out how to make an interactive menu but i don't know how, could someone please help me with this?

i found a loophole and was able to download this so i pretty new to basic, can any of you help me with the questions above? i have a grasp on strings, inputs, and how to get strings to move using the circle pad.

i'm new to this program and want to make a space shooter could someone help? (preferably just put some code or something in the comments)
