You have been locked in the haunted house and you have 13 hours to escape, and the only way you can escape, is by collecting all 13 keys. Or you will be trapped in the house forever.
You must explore all the rooms and meet monsters and give them 1 of 50 items, in exchange for them to leave you alone.
Explore the house and have fun in the games room, but make sure no monsters catch up with you and give you curses. There are lots of curses such as the color curse where all the colors get mixed up, the objects curse where you can't pick up any objects.
