The most important aspect of this game is attacking the approaching fish while avoiding their attacks. When the game starts, fish appear in the sea and the player must control the octopus to shoot them with a gun.

However, the fish also attack the player, who must dodge their attacks. When the player is attacked, their health decreases, and if their health is depleted, the game ends.

Therefore, to achieve the highest score, the player must attack as many fish as possible while avoiding their attacks. As the game progresses, the fish become stronger, making the player's reflexes and strategies more important in higher difficulty levels.

In addition, the player must score as many points as possible by attacking as many fish as possible. After the game is over, the player can check their highest score and time.

This game provides a simple gameplay that is easily accessible, along with a challenging element at higher difficulty levels, offering players an enjoyable gaming experience.

With its simple controls and addictive gameplay, this game is expected to garner a lot of interest from users. Get ready for a fun gameplay experience!
