I played this over Play by Post as a level 3 sorcerer in a subtier 1-2 game.
I had a lot of fun. This was a combat heavy scenario, and it was easy for spell casters to run out of magic. So I kind of cheated and brought my Level 3 sorcerer. I remember playing the Sky Key Solution with my low level Magus and it was tough to choose spells.
An encounter that started us naked was very interesting. Or at the very least without armor. I also liked the opportunities to charm my opponents, since many scenarios don't use charms or ignore Charm Person.
