c'mon guys, it wasn't that hard to figure out. I used to play it all the time, the object was to find the three pieces you needed to make the telephone so you could phone home. They were scattered about in these wells, (the dark green splotches on the light green backgrounds). To get out of the wells, you made the head go up and he floated out of the well. After you got the three pieces of the phone (and in one well made a dead plant come back to life, i don't remeber if you had to do it or not) you go to the screen where the telephone booth dropped you off, stretched your neck, which activated the phone, then you had one minute to move around the landing field to find out where the telephone booth was going to come down
Then you got picked up, and you win. And you see a big E.T. head on the screen, and they play the movie music. Wow,I was so easily entertained when I was young.
