Evazion

To increase your score you need to pop the bubbles. Avoid all sharp spinning monsters to stay alive. The currents change from time to time but there are powerups and bonuses to help you. If you're fast enough you can gain more points by popping bubbles quickly enough after each other.

Rapid Action

Press the bottom small ball to hit the same colored one at the top and score a point. If you get 10 points in 10 chances you go to next level.
