Bubble Meow't

Tobey had a long week and was longing for some relaxation. He decided to spend the weekend on the beach, basking under the warm sun.
Totally relaxed, he failed to notice the tide rising and the waves pulling him into the ocean. He started gasping for breath.
Then, he saw some unusually colored Bubbles emerging from the ocean-bed.
Help Tobey float inside the bubbles to gain some time before he gets help from the Lifeguard.
Dodge the GREEN and PURPLE bubbles containing poisonous Gas and breathe inside the BLUE bubbles containing Oxygen.
But there's also a twist : The clock goes back when inside the Blue bubble. So Play Cautiously!!
Record the highest Survival time and check where you stand against other players in the Online Leaderboard.
CONCENTRATE:
The gameplay is largely based on different colors emerging in short span. So do not get confused and float in the right colored bubbles to save Tobey.
CALCULATE:
Though you are safe inside the blue bubble, the clock, however, goes backwards. So Calculate how long you intend to stay inside and change positions regularly.
