Fixed minor bugs
To win or to play you have to conquer the whole territory. But for that, you'll have to risk coming out of your area, eliminating your opponents and conquering the empty territories and other players.
Of course you also have to protect yourself, because other players also want to win.
When you get out of your conquered space you expose your weak point and if someone touches your tail, or you touch yourself, you lose the game.
Similarly to eliminate your opponents, you must touch the tail for your area.
