The game was alright with a few problems
When you start out small, it's very easy to die and difficult to get those protiens with large swarms of enemies, and when you try to get a large swarm of your own they get eaten almost immediatly. Then when you get larger, if you don't divide, it's almost impossible to lose. Even while you're infected you can eat other microbes and proteins to stay alive, it's almost too easy then.
Maybe if you remake it you can try to make different looking allies and place obstacles that don't necessarily hurt you but are more for the feel of terrain. The powers were nice but it would be awsome to have some sort of power to shot at the enemy. Other than that, the game was OK and good for killing time, so nice job and keep up the good work.
