The Cage of Fetal Movement: Girls Who Have Become Virgin Marysv1.0

The game follows a girl who awakens in a dark underground facility with only a weak sword and faint light. She explores, collecting traces of tragic experiments including writhing entities, defiled girls, pregnant women, and monstrous transformations, pieced together via documents (HCGs) in the form of experiment records. Features include collecting items to explore dark areas with interspecies threats, managing body abnormalities from prolonged medication, consuming suspicious meat for energy (with risks), gathering stained documents to reveal the facility's events, and equipping found items to survive or enhance secret arts. HCGs depict tentacles, sacrifices, breeding, impregnation, pregnancy, predation, violence, and more in tragic and lewd ways. Gameplay uses RPG Maker MZ with ARPG plugin; controls include Q/W for item selection, E to use, A for normal attack, D for guard. No saving in battle maps. Playtime is about 1 hour. CGs are viewable in a post-clear recollection room. Demo available. Updated Nov 26, 2025 with bug fixes and added content.
