CRYSTALSF91'S PROFILE

I would like some explicit information on something I'm trying to make. I'm trying to add a variable each time my character visits a room, and once she has gone to every room, the game ends.

I have Autism, and I want to get the job done right, so please give me all the details, like the checkboxes in the Conditiosn panel of the event window, the triggers, the priority level.
