Avoid Jellyfish

You will control a submarine to shuttle through the deep sea, with jellyfish constantly swimming into the screen around you. Drag the submarine with your fingers to move flexibly and avoid all jellyfish as much as possible. As time goes by, jellyfish will appear more frequently and move faster, and the difficulty will continue to increase. Once touched by a jellyfish, the game ends immediately. No need for complex operations, just focus on evasion and survival —— how many seconds can you hold on?
