Stupid question: From what I played, I know that you can blueberry Sporella and Kari (and I think Gigi too), are they the only ones or is there someone else that can be affected by Blueberry? (specifically Jill or Mari xd)
Right now blueberry stuff is only for bosses. An upcoming area in a future update has NPCs and cutscenes involving wacky blue fun. Full blueberry status effects and abilities for players is something I am saving for anexpansionpack or sequel, once this game is completed.
