Project: Cassian is the codename for a work-in-progress collaborative game design tool written by us. Its main features are to provide a collaborative game design document editor, features for project management, and support for public projects. It is completely open-source and designed for open-source.
This is an alpha.
Project: Cassian is heavily work-in-progress meaning that there are a ton of bugs and missing features. So, do keep that in mind when using it.
