I am developing an arcade fps with no story, no reasons and a female protagonist, her name is Angelica Amadeus, a nun with the power of faith and hot lead storming hell alone for fun. This game is not like Doom, doesn't have linear levels, instead there's 7 maps based in each capital sin.
The goal is to kill as many demons as possible before the timer runs out, you can extend the timer by breaking hourglasses scattered throughout each stage, killing demons quickly starts a combo chain: the higher the combo, the higher the score. Killing demons quickly enough makes the nun enter in "Holy Time"mode, making her a psychopath, her guns stronger and allowing you to gain bonus points during that state. Getting highscores allows you to unlock more maps, more guns and additional game modes. In other words, demons are not the danger, (You) are the danger.
The stages have bizarre gravity fields, if you played mario galaxy it's basically like that but in first person.
thoughts?
