Senpa.io

"Senpa.io is a cross-platform Strategy game where 2 players can team up in the massively multiplayer online action-packed arena. Start as a tiny bacterium, avoid attacks, eat food, and grow to eat other players. With constantly updating features and challenging gameplay, Senpa.io requires patience, skill, and adaptability to become the biggest cell on the gamefield. Similar to other .io games, but uniquely addictive and intense."
