The Game is a 2D single player game(portrait), the task is to pass every level by collecting the required number of masks, sanitizers and gloves which will be specified before each level starts. You should avoid colliding with the viruses around and not to pass near any infected people where a radius will be shown around the infected person.
Collision with the virus is an instant removal in your protection(a bubble surrounding the character/element) and without protection will be a drastic reduction in life. Going near the infected person(in the radius surrounded by the infected person) reduces your protection and then life depending on how close you are to the infected person.
To gain life you will find medicines very rarely in the game, collecting that will Increase your health and to gain maximum protection you will have to collect all 3 elements ,1 each (mask, sanitizer, gloves).
