An advanced save system prototype for Godot 3.1.
This save system can be used in rpg games where the player moves from level to level and the game has to keep track of all the changes to those levels.
The demo constist of three levels: green < red > blue. You move through them by stepping on the yellow arrows. White circles are rigid bodies, their properties will be saved either when you save to a slot (buttons at the top) OR automatically when moving to another level. Red blocks are enemies, they will get permanently deleted from the scene once collided with. Press RMB (right mouse button) to create new rigid bodies. You can also move objects from one level to another, but it's not shown in the demo.
