Sakura Spirit is a mature, entertaining visual novel that is available on the Steam Network. Just in case you are not familiar with visual novels: they can be very similar to a Choose Your Own Adventure, allowing the player to make decisions that will affect the story. Not all visual novels carry a mature rating, but Sakura Spirit is the exception. Even though it has a mature rating, it’s mostly due to the explicit sexual dialog and nothing to do with full frontal nudity.
Sexy game is sexy.
