I'm not fully sold on the Atari VCS yet. I checked how porting goes from Unity to this platform and it seems not too difficult. But anyway, it's been quite a while since the release of Alisa and I'm quite done with it and moving on.
I completely understand entirely. I've bookmarked your game and plan on buying it here shortly.
As for porting your game to the VCS, if there's still any interest at all, it's been pretty straightforward though. I'm helping a friend port him games to the system now
The operating system makes it easy to ingest Unity projects. So as long as you enable read, write permissions and Export it as a standard Linux PC package, then the game launches without a problem. through the development side on dashboard, you can encrypt the file to prevent piracy.
Also, to launch the package you have to create a txt file so that way the system knows what to look for and what data to read in order to launch.
Other than that, there's really no complications here. just build a standard Linux PC package in unity and upload.
