Kalia's Cleansing is an erotic, pen & paper story game for one player (storytaire).
All you need to play is a sheet of paper, pencil, one 6-sided die, this file and a B&W printer (you can also play while watching the file on screen). It's a small and quick game - single playthrough can take ~30 min.
In the game you become Kalia, a young huntress, cursed by a jealous witch. The curse forces any living creature nearby to try and mate with you. Hunted by everyone and everything, desperate for finding the cure, you stumble upon a legend of the Cleansing Spring, that has the power to remove curses. To find it, you'll have to venture into dangerous marshes, fight off lustful creatures, deal with strangers and explore ancient ruins to find the ancient path leading to the Spring.
Make haste, before your will wanes under the curse, leaving you a corrupted, mindless beast, roaming the marshes and copulating with anything that crosses your path.
