Where do you even find the bigger fox sister and cat girl cuz after i defeated the mushroom girl i tried to see if there's other bosses and i found 2 or 3 rooms but they are all empty and i cant go further, there's that room with the floating platform and one with some mushrooms and spikes and i think there was also a third room when you jump the mushrooms down where the spikes are but again it's a empty black room
