About Nautilus Valentinus

Nautilus Valentinus is a free adult sandbox game by Blood-Red Circus, built in HTML. You play an ordinary man thrown back to 2002, exploring a humorous, nostalgia-heavy world shaped by post-Soviet culture, local references, and memorable songs. The game also highlights character relationships and erotic scenes despite its culturally specific jokes. The design uses multiple endings and AI CG visuals for its erotic character scenes.

The current build is v1.45, dated July 15, 2026, and development continues. It runs on Windows and is available in English and Russian without censorship. This update added the English translation, extra scenes with Elenka and Nadya, and improved options and interface adjustments for different monitor resolutions, though Ctrl+Mousewheel or Ctrl+Plus remains the recommended zoom method for HTML games.

Developer's description

"Nautilus Valentinus" is a non-commercial, humorous, sandbox porn game about an ordinary guy who traveled back in time to the good old year of 2002, featuring multiple endings. Important! The game contains peculiarities of post-Soviet culture, local memes, references to certain people, iconic songs, etc., 50% of which will be incomprehensible to foreigners. This may prevent you from experiencing the nostalgia for which this game was created, but this will not prevent you from enjoying the relationships between the characters and the erotic scenes. This game is dedicated to a wonderful person and my partner in game development – wwall. Thanks for everything, my friend. You helped me at a critical moment, and I'm giving you a porn game, so you can become the first person in history to receive a porn game as a gift.
