Good game, needs a survival mode. The virus thing was a good idea, but enemies die too slow or you die too fast. You could probably pop an upgrade system on using points from killing and proteins.

nice game, little short though... 4/5 put in another 8 levels or so and then put some badges on, then it would be a 5
P.S. VERY ADDICTIVE
