Hey, thanks for such a detailed review!!
As for the HP, I setted a variable to tell you that you're very hurt but you can keep going, depending on it(but I'm not sure if it's working correctly). But had no idea how to do an HP bar so... yeah, left it unknown to the player (took that kind of system from Radical Dreamers).
As for Bee, hope you liked the zombie food puns xD Then Bayley was kind of the really cool yet even more friendly guy, while Phoebe is... well, you said it better than anyone lol
Yeah, thing is I tried hard to diverge from Harry Potter as much as I could, since the setup was pretty much it. The idea of you and the bad guy working together was from very early on the plot discussions, so really glad it pulled through well!
