This young man you see in the left part of the game space is a prehistoric inventor and a monkey in the other part of it is his friend. This is the story of their friendship.Very long ago when mammoths trampled down the earth one man lived alone in a cave. Of course, he had relatives and friends, but all of them were far away from him. The reason was simple: they were noisy they didn't let him work and disturbed him greatly, so he left them. The cave man was an inventor and this profession needed his concentration and attention, especially when he was a prehistoric inventor.
