Scare your guest as much as possible with limited money! The more money you make, the more you'll be able to scare them the next time around. Ambience above all - it is the score multiplier. If you're out of money but you have categories still left, you went bankrupt and you must start over. You also must start over if you have the lowest possible score - it'll be impossible to win!
Thanks to GoodNight13 and whoever made "Escape 2" for some of the music.
