House of the Alien ~Creepy Monster House~
Game synopsis
Nina, a student at an all-dorm girls' academy, gets separated from her classmates during a picnic in the forest and loses her way in an eerie woodland. In her panic, she stumbles into an abandoned old Western-style mansion—the very place known as the "Mansion of Monsters." The mansion is home to all manner of twisted, horrifying monstrosities, and they harbor nothing but malice toward the girl who has trespassed into their domain, waiting to defile and toy with her completely.
This is a side-scrolling puzzle horror adventure game. The player controls Nina as she explores the gloomy mansion, solving puzzles in search of a way out. Yet every exploration carries enormous risk—one wrong move and she'll encounter monstrosities of every shape, plunging into an inescapable fate of violation. The game's atmosphere is oppressive and tense, combining horror elements with intense H-scenes to highlight the girl's gradual violation and torment in a hopeless environment.
H-content focuses on extreme play such as tentacles, monster mating, humiliation, forced orgasms, creampies, and childbirth, rendered with detailed CG and cross-section illustrations for a powerful visual impact and a thrill of transgression. The game is short but densely packed, suited to players who enjoy horror atmosphere, tentacles, monster violation, and childbirth-themed play.
