Steam players tag Mysteria ~Occult Shadows~ as Sexual Content, Nudity and Hentai, strongly enough that it is among the game's defining tags rather than an incidental one. Players tag this for sexual content, though Steam does not rate it Adult Only — on Steam this is usually the censored release. Expect sexual themes rather than explicit imagery.
Coilr does not show screenshots for this game. Its cover art is blurred here for the same reason. Both are on its Steam store page, behind Steam's own age check.
This reflects how Steam players have tagged the game, not an official age rating, and Coilr does not inspect game content itself. Valve's own maturity description is on the Steam store page. Coilr users can keep games like this off their public profile in settings.
On Steam, very nearly.

This game's player count is measured about every 24 hours. Steam allows a limited number of requests per day, so the busiest games are measured every few minutes and quieter ones less often. The shape of the curve is real, the fine detail between points isn't recorded.
