I am still alive and kicking, found some time to work on this game, the main tech behind the construction aspect is starting to be usable, still lots of work to do with the physics handling, but it's getting closer. Work has been done to implement basic lightning and occlusion handling, asteroid and procedural generation, but should be more fun to show once i connect the wide selection of ore in the database with the procedural generator associated with them.
