Doable without the walkthrough. I experienced the same bug as DOCX96 the first time I tried the minigame ... It worked the second time though (without refreshing the browser). You might want to look into that. Other than that, it's pretty neat.

The boat mini-game was cool. Kind of tricky (<-Really tricky), but that's what people like, right?
Nice job, I liked the fridge puzzle, but I didn't understand where to find the answer to the mushroom seed puzzle, and even after that, I had to double-check the walkthrough because it didn't quite show the actual combination.
I enjoyed seeing the jester again, I'm looking forward to more adventures from him!
