A thousand years ago, the Maidens of the Sacred Flame fought and defeated the Prime Evil. Now that same evil is once again waking from its slumber in the depths beneath Sinner's Rest Abbey.

Join Scarlet, the last remaining Maiden of the Sacred Flame, in her sinful quest to defeat the Prime Evil. Use your special abilities to harvest sin from your enemies and through repentance, increase your powers.

Explore the ever changing dungeons of the Underworld. Acquire powerful weapons, spells, and items. Engage in lewd encounters with the characters you meet along the way.

Discover the secrets of the Underworld and banish the Prime Evil once and for all.

Explore the randomly generated dungeons of the Underworld. Each time you enter you will find new paths, fight new monsters, and discover new items. Every adventure will be different!

Enjoy challenging roguelite gameplay! Sure, you may die a few times, but each time you re-enter the dungeon you will be more powerful than the last time.

Defeat enemies and complete quests to gain Sin. As a Maiden of the Sacred Flame, you have the ability to gather Sin and convert it to power through repentance. Mistress Julia will "give you a hand" with the repentance part.

Use Sin to unlock new abilities for Scarlet! Create a build that suits your play style. Maybe you want to focus on melee combat. Or perhaps powerful spells suit you better. How ever you build your character, it is up to you.

Increase the level of your companions at Sinner's Rest Abbey. They will be able to provide you with more powerful weapons, spells and amulets for your adventure.

Complete Misty's quests. Misty is a fellow resident of Sinner's Rest Abbey. Her playthings have been stolen and she hopes you will be able to find them. Delivering her lost items will reward you with lewd scenes in Misty's Sex Dungeon.

Engage in sinful acts in the Underworld. Sometimes you will be able to pump out extra Sin from defeated monsters with your magic strap-on.
