Thanks!
For this project the preview is the last public release besides a final Demo thats planned. After that no free releases will be made.
That said, there is a sister project that will basically take the "Preview" game format and make it a main stay. That will be a semi-frequently updated free public project.
But thats on hold because it will use some of the newly rewritten code from Our Apartment. Once thats done at some point releases will start for that project.
