0.3 is the first version of the LUNI Server to successfully communicate with the client. Jon002 and Timtech expanded on this further to release 0.4, which allowed access to worlds such as Nimbus Isle and Nimbus Station.
Characters could be created but not saved or used, and the server could authenticate with the client and load worlds up to 35% (33 and 40% on some worlds). This rendered the game unplayable, although the server was a major breakthrough since it contained RakNet and lots of framework that would eventually come into play when the developers pushed out 0.5 in early 2014.
