Thank you for checking it out! You're absolutely right about the normal souls not having much effect at the moment. We didn't get to implement "points" or a currency of some sort in for the "normal" souls like we planned. So you'd be able to get a high score (freeing the special souls would give you more).
Same with the conversations, due to time constraints we realized we couldn't create enough content quickly enough, so decided it'd be the same questions, just different outcome/replies from each soul, depending on their personalities. Feedback on what could be/is correct can also be improved of course!
I'm happy if the general idea of what it could be came across though!
