Mink's latest hentai game Saimin Gakkyu, or Hypnosis Class, is already a strange (and likely sickening, to many) title in that it has players taking on the role of a hypnotist, manipulating and molesting students at a local school. One of the player's powers is the ability to convince characters to position themselves into headstands, providing for a below-the-waist view.

Failing to release the “headstand mode" before clearing the game, however, leaves the girls locked in this position in subsequent playthroughs, according to salacious Japanese culture site Sankaku Complex (NSFW). Thus, players may have a difficult time telling characters apart, seeing everyone upside down. I suppose this is a boon for foot fetishists, though!
