It's a cute game, but it's sad that you think a "girl-oriented" game involves finding the man of your dreams, and that the best way to be happy is to be with a guy. If you want to attract more female gamers, give us a female protagonist who does something worthwhile (like rescues her daughter from zombies), not a character who dates different boys and gets rewarded with clothes.
I wouldn't be offended if you hadn't said that you were trying to appeal to women.
