Digdig.io is a very fun io game. Your task is to move around and collect water to grow. Collect other resources to add armor to make you grow faster. Remember that lava will drain your life. As you get older you move slower, stay away from opponents bigger than you, they can knock you out instantly, and when you're old enough you can start battling other players for extra points. Pay attention to your health and armor when facing other players. The red areas will make you stronger, so go and absorb them. The game is simple and addictive.
