Defend the cell wall against waves of viruses and bacterias! Both classic and unique elements of the Tower Defense genre are combined in Cell Planet.

– Drag and drop skills to damage or immobilize the bacterias, or even heal yourself
– Touch or slide the screen to collect resources for skills and leukocytes
