Nice game. The only ones I got wrong were "give" instead of "please" and color" instead of "help"
I too had the same problem.
I got colour instead of help as well.
In other conversations, like the one before you save the cat, waatu was used too, so it couldn't be "color".
I've already saved the "kitten" which I named "cat" so I didn't realize that dialog also used "help"... I think a replay system in the notebook would go a long ways
