You start as a small capybara with a score of 1, swimming freely through the ocean and encountering various marine life.
When you touch a fish or marine life with a score equal to or lower than yours, you absorb it, increasing your score.
If you touch a creature with a higher score or run out of oxygen, it's game over. An oxygen gauge appears on the left side of the screen, and it decreases over time.
You must surface to replenish your oxygen before it runs out, and this oxygen management is a crucial strategic element of the game. Furthermore, absorbing 10 marine life triggers Fever Time.
During Fever Time, your oxygen will not decrease, and you can absorb any creature regardless of your score, allowing you to experience the thrill of rapid growth. Marine life with various scores appear in the ocean, and the more you play, the larger creatures and more dangerous situations you encounter. Simple controls and intuitive rules make this game easy for anyone to enjoy,
but it offers deep gameplay that relies on oxygen management and movement strategies.
