Gameplay
Referred to as "control", the player views events via hidden cameras set up in eight different locations, which can be viewed one at a time. As the aforementioned Augers creep into the house, the player has to spot them and use traps to capture them. At the bottom of a screen rests a small meter; when this meter fills, it is the player's signal to activate a trap in the room being viewed (i.e. a revolving bookcase or a faux seal on the floor) and capture the Auger(s) on screen, adding to the score.
The player must also have the correct security access color code selected on screen in order for the traps to work. The code is changed four times throughout the course of the game, and keeping up with the accurate code requires listening in on key conversations. Ultimately, high performance requires repeat plays in order to gain complete knowledge of the story and capture all Augers possible. Time always moves forward, cannot be rewound, and if too many vampires are missed, the game ends. The game will also end if certain characters are taken away or if the hosts of the slumber party disconnect your access to the traps.
The game is an example of the trap-em-up genre, which also includes games like Heiankyo Alien, Space Panic, and Lode Runner.
