In my humble opinion it is like if this game lacks of a purpose: in Succulence 1 Serena had a task to accomplish and most of the game was focused on that. Instead in this game i don't see what is the real Serena's task: yes the succubus of Succulence 1 escaped and there is the Dreamworld to explore, but that is all, because in the Dreamworld you can only explore its various sectors, fighting (or avoid to fight) the policewoman manifestations and gather the various orbs put here and there. I feel like I'm going ahead, hoping everything will make sense in future, but without a clear idea about what I'm doing and why.
