The better question is, are any of them
any good? Pigs in Space for Atari is the only one that I've played that's remotely enjoyable. And that's because it's stolen games.
Chaos at the Carnival is just terrible on all counts. When the levels are actually fun, they go on too long. The controls are crap. A 5 foot wide Kermit has to navigate through 2 inch narrow rock openings. And when and if you even get to the last level, the controls go from terrible to *&^%$!!!! as you have to push a giant monster off a cliff with a feather in the most awkward way possifreakingble.
Oh, and after all that headbanging wonder, you get rewarded with this...
In character, yes. Also annoying as crap to be
insulted when you win a terrible game.
