The princess's story/romance will mainly be in act 3. The game right now, is currently in act 2.
I'll move onto act 3/starting content for the princess, once Lenya, Cecilia, Violet and Jasmine's stories are concluded with the main villian of act 2
will this game be split after act three or will it be complete what i mean by split is like a separate game or will it end with act three
I'm not sure yet. Depends on how large the game size gets. If it gets too big, I might split it.
