Our decision to present an all-female cast is a stylistic choice based upon source material such as Touhou Project, Deathsmiles, and others. These games form a subgenre of shoot-em-ups known as "cute-em-ups", which heavily inspired Bullet♥︎ both in terms of gameplay and aesthetics.
In our design process, we've endeavored to create powerful, three-dimensional characters for fans to enjoy, regardless of their gender. We think that we've done a pretty good job of this, and in testing we've had positive receptions from gamers across genders, ages, and nationalities.
Bullet♥︎, its characters, and its artwork are appropriate for ages 13+. In terms of content, the storylines and genre fall squarely into pulp-action.
