Very fun idea! You say the name and you pretty much understand the concept immediately. It seems easy to pick up and play. I like the premise of making it 7 days. I can easily imagine each session as one day with some sort of threat to be dealt with or if we wanted to, we could do the whole week in a single session.
Fun theme and there’s good prompts when creating characters to help players help build their world/school/relationships quickly so everyone at the table can feel part of that world.
