This is a pretty solid entry. The graphics look really nice and the music fits the game really well. The way the big white blood cells are introduced after a bit of free-reign over the reds works well. They are nice a big and somewhat terrifying.

Thanks for having a controller option though it took some trial and error to figure out the dash button. Controls felt smooth and it was pretty satisfying to see how efficiently I could graze the red blood cells to infect them.  Great job with this.

I love the way your background sets back and allows the foreground to pop!

damn! this game is addicting and fustrant XD. very nice, i love it

I really like this one too. I never liked white blood cells, but now, i hate them. :-D Its kinda difficult, but i like that. Maybe i will implement a combo mechanic in my game as well. Maybe you could add some powerups or different viruses to play.

The game's awesome.
