May I suggest thinking of a story BEFORE creating levels?

As for a story, do something SICKENING!

Like, my story. Well, you know it. Spaz got phonecalls from 'Devan' *cough cough* and all of a sudden, Jazz gets 'evil' *cough cough* and then you have to unravel the mystery. I hope the 'coughs' didn't gave away TOO much info...
