The function keys have all the words I understand except SCORE and LOOK which you can type at any time.
The way to get a high score is to collect as many objects as possible and leave them in your cave or carry them with you. The game ends when you find your tribe again.

Thunderstorm bug. Randomly occurring thunderstorms will cause the caveman to drop everything in fright. This doesn't reset the number of items carried so your normal limit of 6 items rapidly decreases.
What a dreadful, dull game...
