So I was reading the wikipedia article on H2O ~ Footprints in the Sand and it mentions a rather unique feature of the original game, perfect for when you are caught in the *ahem* act.
There is an additional “emergency” button that can be activated if the player does not want other people to know they are playing an adult game. This option shows a random piece of artwork unrelated to the game’s content out of around one-hundred images. These images are rather bizarre, one such image containing a black and white photograph of a toy horse head with red “blood” splattered around the edge of the image
Cause as everyone knows, violence = good and sex = bad. Not even a severed horse head can change that. Instead of a questionable emergency button, I think Hayami has already shown us the correct reaction for anyone caught playing an eroge:

Truer words have never been spoken.
