The first idea would be that player have 2 or 3 lifes. I can make the textures for it. They would lose a life when got kill.
Yes that could be interesting. I think I'll make many things configurable through the yet-to-code-and-design GUI, so I'll make sure that one can select how many lives each player should have (it will also be useful if we make a singleplayer/RPG mode, where we don't want to be able to lose the game so easily).
