There is no official roadmap yet but I can easily sum up our immediate goals. As it is we're quite happy with the general state of the game and engine, there's a couple of bugs to fix but otherwise nothing significant development wise that requires urgent attention. So yes, a beta release is imminent. As of now we're focusing on content for Exanima, this includes new encounter types, more environments and more items. After some early steps for the new content our focus will shift towards game features such as the skill system, introducing some thaumaturgy, new combat manoeuvres and animations, new interaction mechanics and extending our AI behaviours. An additional goal is to add some kind of tutorial as the learning curve is incredibly steep.
We do think some of the additional content is a top priority but adding content and features is something that will continue after the Steam release and alongside the develoment of Sui Generis.
While it may not be very apparent in terms of gameplay the recent changes we made to significantly improve performance and support large persistent worlds involved some drastic changes to engine and game systems, chaging systems that are already in place is always problematic. That's behind us now and future updates to Exanima will come much more quickly and smoothly.
There is a lot of misunderstanding and criticism surrounding the game but honestly it looks like that's unlikely to change until Sui Generis is released so I think we're just going to have to live with it.
