Play Any Level
If you are playing the game again after a long absence, you may not want to work through the whole game to reach your favorite section. The good news is that you can do a quick cheat to take you to the level of your choice. Go to the "Options" screen and use the analog stick to press "Up," "Up," "Up," "Up," "Down," "Down," "Up," "Up," "Down," "Down" and "Down." Start a new game and you will see all the levels available to you.
Get All Power Ups
Play the game with all the power ups available to you. Go to the main opening screen and use the analog stick to enter "Down," "Down," "Down," "Down," "Up," "Up," "Down," "Down," "Up," "Up," "Up," "Up" and "Up." When you hear the sound of a sheep, you will know you have entered the code correctly. Start a new game and you will have all the power ups available to you.
Resist Damage
The life indicator in the game doesn't really reflect the maximum life you can carry. Start a level with full life and avoid taking any damage before collecting extra lives. This will stop you from taking so much damage when you are hit and it works on every level.
Collect Extra Lives
Before challenging a difficult level, it can be a good idea to build up on lives first. The easiest way to do this is to return to the first level and go to the crib. Inside you will find an extra life. Collect it and then exit the level. Now return to the level and do the same. Continue doing this, collecting extra lives and exiting the level, until you have built up enough lives to challenge the harder levels.
