space + arrows = expand territory
Infestation process has begun! Biochemical experiments went wrong and all parallel worlds of this universe are being under attack of the agressive viruses. We must stop them in their expansion by limiting their space for their growth. So let's limit their living space and we should be ok. The deadly bacteria are trying to take you down as you try to claim enough of the screen for the safe zone. Avoid the viruses as you weave around to grow your territory and fill up enough of the screen to complete each level. Have fun.
