This game is more frustrating than fun.

Once the game is beaten, the additional levels hold nothing back at the player. At times, about 80% of the screen is filled with antibiotics, making it mandatory to get your immunity up. However, the white blood cells are many, big, and can move about, meaning you need the strength and manpower (viruspower?) to take them down. This is where the issue begins, the antibiotics can make the field impossible at times to even see any white or red bloodcells. Because of the number, white cells can wipe your entire viruses team out the moment they form.

I can take out one with about two or three viruses. But if six viruses form the moment the White cell is over them, they're all gone.

Don't get me wrong, I like the concept of the game, but it can be relentlessly uncaring at times.

Just too random, hard to plan or do enything when is no see red cells and everywhere is antybiotic.

Reasonably hard and challenging.

FFFUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU

too much of this game is dependent on random generation, half the time if you are just about at victory you can lose if a resistant germ spawns all non resistant who then by chance blow into antibiotics ending the game forcing you to start over that and it is hard to determine exactly when a white blood cell will bump into you while dodging. Fun game but after a while it gets annoying since constant death punishes you and slows things down making it feel more tedious than fun.
