Oh I'm in love with this! I can see this being a really big puzzley game, like with branching storylines and everything. Maybe if you have plans to make this a full game, there could be something where you have to talk to other spirits or explore places when you're not in a seance? Like Ace Attorney if that makes sense? That might be too hard to make though haha. Either way I really really like this whole concept and I would love to see any sort of continuation! And I really want to help these guys figure out their mystery!
