Shadwen comes with a level editor for Windows that allows you to create your own levels and publish them for other Steam users to play.

We've also created some some playable tutorial levels for the editor that teach you how to get started. When you open up the editor, the editor tutorials should automatically open. There's also lots of info and instructions about the editor in our public wiki: http://frozenbyte.com/wiki/index.php/Editor

Naturally our support team is also always happy to help you with any editor related questions! You can contact us by writing here to the Steam Community or send us an email: support[at]frozenbyte[dot]com

Looking forward to seeing your levels. :)
