Okay game but needs work
This is an okay game. The concept is interesting. (not many games where you get to play HIV) But it needs work in a few ways. The mechanic is a bit simplistic. but that might just be my view. The other parts are structural. White blood cells are not damaged by most viruses. Choose one and name it. If it is HIV it only attacks the white blood cells, not red. Whatever it is, it is a virus, so antibiotics aren't going to help anything.
Do a little research. Understand the thing you are trying to model. Until you do the model will always be flawed.
