hearts--;

alert("You battled a Grublor and were hurt in the battle." +

" You lost a heart.");

We used a bit of Javascript magic to remove a heart. When you have a variable that contains a number you can add a double minus sign to the end of it to subtract one.

Note: If you add a double plus sign to the end of a variable that contains a number it will add one.

Try it out:

var test = 1;

test++;

alert(test);

The last if/else is very important. If the player still has hearts after a battle, you show screen two again. If the player's hearts are less than 1, then you show a game over message.
