Saving the World

I ve just released the game, based on Minecraft gameplay (Kopatel 2d)

And I have a question if a player want to save the world in the game that he made. So when he closed browser and then open it again, all block should be exactly at the same position when the player left the game.

Any ideas?

Try saving it to JSON using the Array object.
