All Animation Is Disney: Despite being 2-D animated, the game itself has been bashed on by gamers as well as the reviewers for criticizing it for its art style mimicking Disney. It seems to be heading towards Don Bluth and Richard Rich's work.
Contested Sequel: Nowhere near as much as the universally-reviled King's Quest: Mask of Eternity, but it still has a large number of detractors who don't like, among other things, the changes made to the King's Quest (and early-to-mid Sierra adventure games in general) formula, like the lack of Have a Nice Death, a point system, and the addition of chapters, which can be played out of order.
Genius Bonus: Lord Tsepish's name is a phonetic spelling of the Romanian word tepes, or impaler.
Guide Dang It: The final puzzle. The magic wand that can change the impostor troll king back has two settings, T and F, but unless you mouse over the one pixel at the bottom of the wand you'd never know. More annoying is that since it's a wand to change something back to its own shape, you'd think the T and F stand for True and False. Nope, they stand for Troll and Faerie, so using the wand set to T on the fake troll king won't work, and you don't find out that the false king is one of the faeries until after you change him back.
Nightmare Fuel: If you take a long time finding a way out of the coffin, the skeletons around it will start trying to force their way inside. If you take too long, a skull will poke through the wall eagerly. Cue the "You Have Died" screen.
The Boogeyman's theme is this for some people, but others find it to be just an upbeat, catchy tune.
