This game saves, when you place blocks! This is a concept for you if you like to make a world that saves building progress.
Downside: The game does not save the blocks when they are MINED, If you mined a block, It will still be there in the next gameplay, We will fix that soon. And the more blocks you place, the more time the world will generate. 0 blocks would just load the world instantly.
NOTE: There is a bug/glitch that doesn't allow ALL the blocks to save successfully, Leaving out many blocks unloaded.
