thx. yeah IG changing the character design is easy.
Also, setting DO work, but for some reason they reset when you enter the menu again, so.... Yeah do your settings and never enter again until I find a solution for it.
Actually the settings menu is getting reset probably because it's not programmed to load the currently saved user setting, i mean are you saving it in any variable, i mean the music and screenshake setting? If yes, you need to change the values of the input field (On/Off) in the settings scene according to the values of those variables when the settings scene load. I don't know how to do it in GDevelop, but in Godot and Unity, its possible easily, I'm sure you can find tutorial too on it!
