You will need to be courageous and fulfill your mission. Good Luck!

HOW TO PLAY
This game is for one or two players. As soon as the video game turned on, the option is only 1 player; it works only on the right side. To change to 2 players, use GAME SELECT. To return to option 1 player, use GAME SELECT again. The indication for two players is the score for 1 player (in the upper part of the screen) is blue and yellow for 2 players. DIFFICULTY in the A position makes the pogo stick more easy and at position B more difficult.

Move the caveman left, right, down or up bypushing the lever of the joystick in the direction desired. You should always escape from the dinosaurs. For throwing stones at dinosaurs, hide behind a stone and then move the joystick in the direction that you want the stone to go by pressing the button. If you throw a stone and it has no place to go, this will turn into powder and disappear forever.

If you trap a dinosaur surrounding the stones he will be trapped only for a few moments. When you least expect, the dinosaur will escape through the stones and begin to pursue you again. You can stay in the past only 75 seconds. After this, you lose the game. You must kill dinosaurs within the specified time. During the last 15 seconds, the stones will become blue for you to know that within a few seconds you will be transported back to today.
