It's a tiny additon, making a huge difference in how the game plays out. We've experimented with giving each player 'Extra Lives'. Each time an opponent is defeated, they will lose a life and respawn in 3 sec. Opponents are permanently defeated once their lives are spent.
Each player start off with 3 Extra Lives by default. You can turn off Extra Lives by setting them to 0 in the menu.
We'll be testing this in beta until Friday - feel free to check out the beta branch on Steam before Friday to check out this new feature!
