Larger Maps? Better map building? - Spellwizard/PortfolioBuilder GitHub Wiki
By figuring out where a player is now and then as they move to the left by X pixel positions the next map in that direction is read by X pixels and drawn. This might be done to make editing and swapping parts of the map easier
adding a mouse + click mode allowing blocks to be added to the game also with drag and hold to make lots of blocks and storing it all as pixels and therefore savable into a map
