Could not complete this game due to glitches. In level 6, one virus remained in the cell. Had full defensins, lysosomes, and slicer enzymes. In level 8, deployed 100 toxins, and the objective suddenly dissapeared. Faced countless levels of viruses after the toxins had been deployed, with not ever being able to move forward. Not being able to finish a game really ruins it for me =(
I have a cheap laptop that is a couple years old. I had NO LAG. Not even for a second. I would imagine those complaining either have an old-as-dirt computer or are in need of updates. Computer 101: Close unused programs; Don't allow Windows to update when you are playing games; frequently check for updates--such as browser and flash player updates; if your computer acts erratic--do a thorough virus check with a renowned program.
Fun game, but where is the explanation for what's special about each balloon? I made it to level 19 without losing lives, then these 5 white balloons come out and I lose ALL of my lives.
