That jumpscare only appears once in the whole game, and it is only in the intro to the first shift.
It is a part of the cutscenes, the game has a much bigger focus on the erotic aspect. That jumpscare doesn't really ruin much, and since the game goes for a half parody half creepy approach, we decided to implement it. It doesn't ruin the experience, the game's erotic focus is still a much bigger focus and those jumpscares are scripted and do not happen during the erotic sections of the game.
