Mini Game - Secure Lock

Just a One Day Godot Training (UI Create) Project, which can easy plug in to other project.

bug fix? sure, that why I make this.
SE? maybe after.
BGM? no.
game feature update? maybe while I got motivation and idea.

maybe merge to other project or add other mini game into this project IDK.
but it should be a mini game inside other project

-> next fix: screen size in mobile device
