Evolvo Plus is an arcade game in which you play as an evolving fish. Eat fish that are smaller than you to grow, but stay away from larger fish, which will eat you! Also, watch out for hazards, such as water currents, mines, toxic waste barrels, and nets. Level up by eating enough fish; you can upgrade your speed and agility, or evolve when you reach a new level. When you evolve into a new creature, you will gain a special ability.
