Thank you! I also thought at that time that it would be a waste if I do not make a menu for this, and so I added those scenes.
Also the way it works is that these texts are not button at all. They are Area2Ds which names corresponds to the next scene they will go into, and that moon has the Area2D to detect them.
I never implemented that kind of menu system before so it was really fun experience (big deal for me frankly haha)!
