Amoeba

You're an Amoeba and you have to survive in a dangerous microscopic world for as long as you can. Move around and collect the glucose cells to stay alive, but avoid touching the viruses or you'll lose health. As you continue to collect the glucose cells, more and more viruses are added to the field, increasing the difficulty. But you can collect the different power-ups that appear randomly to stun, kill, slow down and shrink the viruses.
