The Blue Moon is Dyed by the Abyss

Kosuke and Aoi are childhood friends who have harbored romantic feelings for each other since youth. After Kosuke finally musters the courage to invite Aoi on a trip, she accepts—and it seems the two are on the verge of dating. However, their romantic getaway takes a dark turn when, at their inn, Aoi becomes the target of men with ulterior motives due to certain circumstances. The game follows the unfolding of these events and Aoi's fate. This is a dot-animation game focused on erotic scenes rendered as detailed pixel animations. The game features a choice system that lets you replay animations, with toggleable cross-section views. Content includes netorare (NTR) themes, blackmail, voyeurism, and various sexual scenarios.
