There will be just one update with Apartment level for old game but yes, LSH ringman will be worked on from now on. There will not be a skill tree but you can modify speed and stamina by eating food. There will be a charm in future to grant more speed. There are ways to modify climax time too. Well hints are available in game. Like hints for most secret ghost can be found in SCM Database page on web browser. Rest will be told my NPC's or documents lying around the world. If you are miss any of them other who have found it will answer.
