Thanks for the review! I will add a tutorial. For saving a person: if the person is in red colour that means it is infected. Just go close to him and there will be a text popping up, press K to save the person. You need to press K and the person will be back to normal colour and start walking. But make sure you are fast enough, don't let the covid meter fill! Otherwise you would get infected. Thats how the game works.
