So... click flag to start. Select a difficulty level. Choose a player by pressing space. Then press the up arrow. Use left to move left, right to move right and down to go straight ahead. Avoid the yellow bombs. If you touch a bubble(blue ball) you restart the level but collect one bubble. When you click on the bubble at the top, you get to pause the game for as many seconds as you've got bubbles. When you get hit by a ball you lose a life and the game pauses for 3 seconds. When you have zero lives left, it's game over.
