If you think that high buildings are an invention of the present you might be mistaking as the cavemen in this skill game surely have some tall structures hanging around. A great way for them to make time fly was to jump from one wall to the other. They did not have TVs or computers back then of course but you will find that it is quite fun to do so, especially as there are quite a few hazards that you need to stay away from, such as bricks that are lit on fire, spikes and flying knives. Rest assured though as your friend the caveman will be able to collect some bonuses as well, in the forms of boots of speed and shields.
