I plan to make approximately 15 characters. 3 to 4 will be men.
About the characters awareness of the MC be in a harem... Wooow!... in fact... I haven't really thought about that ๐๐๐ I think the characters won't have that in mind at first, at least during the early parts of the development.
My idea is to make sure they don't commit and everything just happens, like ecchi anime! And then... when the game have all the characters... all the scenes... the gameplay full working... maybe I'll put a jealousy system and some cool mechanics. Not sure about that yet ๐
