In Bugs Sim you compete against AI opponents to complete the map goal(s) before they do. You do not control your bugs directly! Each bugs has their own level of energy and hunger which they indicate through their thought bubbles. When they get tired, they sleep. When they get hungry they eat. When they are rested and full... they wander aimlessly!

You can place plants which grow food that your (and your opponent's) bugs can eat. Want to stop an opponent's bug from eating from your plant? Throw a sticky in their path to slow them down!
