Trivia
The opening sequence (with the words floating by each other) is a parody of the opening sequence of the movie "The Terminator". When you select "Return to Demo" from the options screen, the story that's shown is an obvious parody of the "Star Wars" scrolling text opening sequence.
The song "Eat Your Veggies" in the Well of Wishes level actually was written for Keen Dreams, but was removed from that game to save disk space. Explains the name, now, doesn't it?

2. a) Go to the Pyramid of the Moons.
b) Climb down the second pole to the right.
c) Go in the door and press B, A, and T simultaneously, which will give you the yellow gem automatically.
d) Go right and unlock the door.
e) Walk further right and hit the switch.
f) Walk around slowly back and forth to each side of the whole room, so all the inch worms collect around your feet.
g) A huge foot will appear. Touch it and it takes you to the secret level.
h) Beat this level, and read the janitor joke that appears.

Developer Tom Hall on the creating the infamous Dopefish:
"The Dopefish, upon reflection, is pretty much based on one of two little faces my brother, sister, and I would draw on everything. Except stuck on a fish. I guess they were sort of the emoticons of the seventies. And of course, he's inspired by the Ravenous Bugblatter Beast of Traal from The Hitchhiker's Guide to the Galaxy. That's why they're the SECOND dumbest creature in the universe."
