The fairytale-gothic mix is good, the mechanic for Prince Charming, and the level-scaling formula make it an iteresting and unique boss-fight.
My biggest perplexity is that i cannot understand clearly what system is made for, someone in the comment says Pathfinder but I couldn't find a line in the module. Also, a few stat entries have missing values, sometimes it says the modifier, sometimes the value and it's a bit confusing. I know the space is limited, I had to cut a lot from my entry, too, but adding a short sentence description or roll table for the buildings not present in the map would make exploring the town easier.
