Just beat the Blaze path (I thought there would be more fighting) and it's definitely quite an impressive three path game you made here. The mysteries were not too tough, but the triggers could have used a little bit of work. For example I tried to leave the vampire castle and Blaze said I had to talk to the vampires, which I already had. I had to talk to my fairy friend to trigger the exit. I also had to talk to both the vampires in the castle, even though the one I spoke to had already given me the information I wanted.
Little things like that make a game of this type more confusing, as one doesn't know when they missed some arbitrary trigger, or if they are missing a real clue. Still, it didn't take too long to figure these things out, and roasting the guilty parties was pretty fun at the end. Wish I had time for the other two paths!
