This is an agile game that mimics how viruses destroy cells in the human body and how cells destroy viruses. Players manipulate cells to evade virus attacks and seek opportunities to eliminate viruses while avoiding them. The player tilt the screen to move the cells to avoid the surrounding viruses, and seeks the opportunity to devour the antibodies that are beneficial to them to eliminate the virus while avoiding. Antibody 1 makes the cell move faster, antibody 2 makes the viruses slow down, antibody 3 kills a random virus. When the virus collides with the cell, it will be swallowed, deducting a life value, and when the life value is 0, the game ends. In the process of avoiding, other cells will be encountered, and after phagocytosis, their own life value will be increased.
