On the title screen, press: A B right A C A down A B right A

If done correctly, the caveman second to the right will grin. Now, start the game, enter the first level, and press and hold A+B+C, all together. Release, hold down A, and press up. You'll skip to the next level, and you can perform the ''hold A press up'' code again to skip multiple levels if you wish.
