thank you so much for the feedback
I do have plans for "difficulty", some sisters will have considerably cheaper prices than the ones currently in the game, so if you want to win early, they'll let you do so.
I'll look into the music, shouldn't be too hard but then again the game is kinda hold together via duct tape lol (artist brain)
VA is quite pricey, if I ever add it I'd like to be in japanese, there's a lot of VA from Japan I'd love to work with, but that'd mean adding a jp localization, which is even pricier than the VA itself...
