How do I get rid of the purple one quicker? they take forever to get rid of and they completely swarm me after awhile
Better yet, Don't. Ignore them and let it saturate in the beginning. only so many appear, so if you max it out with the little guys you don't have to spend a single cell on Enzymes. It only takes a little extra clicking in the beginning but is massive savings, both in damage and defense.
I should probably clarify this doesn't work if you intend to Transend or if you close the game. You can focus killing the big ones and letting the little ones swarm though.
