Fun to play for a while, one to play when ur bored
You had a nice, different, unusual idea for a game here and it worked, it was fun to play, but after about 5-8 levels it gets a bit boring, as it's pretty much the same old stuff over and over, apart from the fact that the only real change was the antibodies and white blood cells being added. I liked the idea that you could level up certain aspects of the virus after each level by collecting so many points. It could have used some sound effects for when the viruses take over the red blood cells, and for when the white blood cells and antibiotics got the virus. Maybe you should make a secquel to this and have more antiviruses and stuff in it and maybe some other new ideas as well, if you do I'll be looking forward to it.
