So project should be back on track soon TM.
The project is planned to have a major overhaul.
Chapter 1 will be extended, though what existed before will be more or less unchanged.
Chapter 2 will mostly be the same as it is now.
Chapter 3 and 4 will be redone from scratch gameplay wise.
Terrain will mostly remain the same, at least theme wise.
Heinvers and I are still talking details, so subject to change.
