Ayane: The Pregnancy Planet

You control a sentient sperm cell in a surreal arcade-adventure set inside Ayane's alien body. Ayane, a reproductive-mission alien from a distant planet, has crash-landed in the protagonist's lab. The gameplay involves navigating her internal systems, evading white blood cells (Antis), collecting genetic material to upgrade your abilities, and racing to fertilize her egg. Success unlocks new intimate scenarios. The game features a ranking system that scores players on conception speed, DNA collected, upgrades earned, and survival, framed as a competitive prowess challenge. It's a humorous, anatomically-inspired survival game with explicit adult themes.
