The demo is now ready for download. As I said, it is invitation only, so email me if you want to play.
There is a readme in the games directory which you should read first.

This isn't a lot of actual gameplay in this demo. It is mostly designed to implement the character customisation and player interaction features, which are the foundation of any online game. Players are able to create a character, and spawn into a large island world which they can explore, and communicate with other players.

The game is only 160 MB's in size, which should take long to download on a broadband connection. Since it is an online game, you will of course need an internet connection to play it. If you're worried about security, no information is stored about any players, (with the possible exception of the player's IP address being stored in the server logs) and the only information visible to other players in the character name and options you have specified.

So, if you want to be the first to play Spiritus Astrum, send me an email at:

Also, if there are any bugs, suggestions, or comments, feel free to email me as well.
