DuoPrincess is an excellent action game by EasyGameStation, developer of Gunners Heart and Ele Paper Action. Basically a beat 'em up featuring 2D sprites in a 3D environment, this doujin release features two selectable characters with different magic spells and abilities to use in combat.

Attacks are executed using the Z key, while pressing X will cause your character to jump. Magic is cast by tapping the C key, although this action will use up some mana. Fortunately there's no need to drink any potion as your mana will replenish automatically in a matter of seconds.
