You play as nano bots, competing to control deadly (but weirdly cute) microscopic creatures that are out to kill you all.
You slowly lose energy. The only way to regain energy is by eating the small gray energy pellets.
Your only weapon is to convert the creatures to your color and make them hunt your enemies, but every time you do they multiply.
Gather strength, make your creatures attack at the right time, and win by cutting your enemies off from their food.
