Click the green flag several times because the basilisk likes to disappear this ain't the big games i'm talking about making, but it's a kinda fun game, I suggest trying a two player two round battle to make things less crammed. and, just press 1 or 2 or 3 or 4 to attack(depending on what player you are)! You can only attack when you are close to another player.
you have to click the green flag twice to get the basalisk to show after it's been destroyed.
