So you make a game with 6 (!!! A more than decent amount, mind you!) girls, each with her own route, which is already a massive game and a LOT of girls to pick from. Put them all as the main girls, and develop them.
Once we're interested in them through story/art, you just drop 9 fucking side characters for no apparent reason (2 have the excuse of being family at least, though only Katie ever gets any meaningful development), and then we wait a year to get minor content with them.
The game development is blueballing me harder than the dev is blueballing his own MC and that's kinda wild.
"My Girlfriend's Friends"... & family & other unrelated women she doesn't know about.
