Add a singleplayer mode
Currently, the game is only playable in multiplayer mode. A singleplayer mode would be cool, but also extremely difficult to implement. One possible solution would be to write an integrated server using classy (the godotcraft classic networking library). This would be beneficial, as it would allow users to easily host games on their LAN and join using another device. Alternatively, the lazy solution would be to simply integrate classicl-server (or a fork of it) into the project (or maybe download it when needed?).
