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.One day he made a net. It was thin stripes of bark tangled up chaotically. The net appeared to be a useful invention as it was simple to catch birds or small animals with it. But once the man discovered a little monkey in his net, it was so defenseless and cute that his prehistoric heart took pity on the animal for the first time since people lived on the Earth and the cave man took the monkey home. They lived in harmony and they were the happiest couple in the world. All day long the man was making new models of axes, spears and knives and the monkey was sleeping on the nearest tree or eating insects. Sometimes they did something together, for example, they loved walking and playing.
