While it is hard to judge a barely completed video game, and one for preschoolers at that, I have actually played (if that's the word for it) an emulation of this game and... well... This person's video can explain it. That's right. The game is little more than a kid's keyboard with jerky animations of Grover having convulsions and impersonating Frankenstein. I'm guessing the project was abandoned when they realized how frightening a zombie Grover lumbering around to music would be to the target audience. And at least with other Sesame Street titles... you actually can DO something.
