This is so hard to do 😭😭 It took me almost a week and only got this much. But I am surprised how much flexibility Godot UI had. I wouldn't even dream of making stuff like this in Unity. I still don't know how the selection effect(the red and blue thing) works. Here's the itch link to play around with (When opening Menu for the first time, it will have a really long load time. might be able to fix this if I load it at the start of the scene. because there are some problem with the shader compilation speed for Godot on web I think)
