* New actions are available to save & load the game state, making Saving & Loading as easy as adding 1 action to your game! * While it will work in most cases, it has a few limitations and hasn't been thoroughly tested on all types of objects/behaviors and games, so it is for the moment tagged as **Experimental** while we gather feedback and improve it * Check out the wiki for more info: https://wiki.gdevelop.io/gdevelop5/all-features/save-state
