Road

Level 1: As soon as you appear, jump right and kill the two sword bearers. When you have done that, jump right again and you should be on the first stone slab. Walk to the end of it and jump right again onto the second slab. Walk to the end of this slab and jump right. Then walk right and voila, you're on level 2.
Level 3: Now walk on right to level 3. This level is a lot easier than the second level as all you have to do for most of it is jump the barrels. As soon as you appear, jump right and keep the joystick in that position and you will find that you will jump all the barrels till you reach the wall that you have to jump on to. Soon after the wall comes a hole which if you fall into you lose a life. Once cleared of this hole by jumping it, jump right over the rolling barrels and Walk right to level 4.
