Haha, the difference between the tutorial and the first attack is fun.
Nice game, the movements of the following cells are a bit slow in my opinion so I was more dragging them toward other cells than commanding an attack but it was not so bad.
The little bug on death and the one on the UI were already mentioned before. Before the first infection there is a component that I cannot pick, right before the three stacking cells.
I have not found anything game breaking so good job !! :D
It would have been really fun to have more varieties of cells and maybe a score ;)
