It's simple, swim through the endless ocean and collect garbage!
But be careful, along the way you can meet aggressive sharks.
For every 5 garbage bags collected you will get 2 coins (5 garbage = 2 Coin). If you get enough points you unlock more oxygen time, you can buy 15 minutes of oxygen with 500 Coins.

Having 500 coins is almost impossible but if you do you will have 15 minutes of oxygen.

Compete with people from all over the world and become the TOP 1 in staying alive in the game the longest without dying!
