I wish they had more to it,
It ended far to quickly and I wished you could do more with the lab. You had to stay within the confines of the game. I liked it so much I wanted a 3rd version. Like the guy above, After winning, there is no challenge to go back and play again, as you know all the answers and the challenge is gone. The adventure story games like this are great fun without putting too much time into it. You can come back to the story without having to learn a lot of hard stuff just to have a relaxing time.
