Santa vs. the Snow Goons

Help Santa avoid the snow goons! 

The snowmen at the north pole are running amok!  Fortunately, they're not very bright.

Mouse Controls: click a neighboring square (or really, just click the field in any direction) to move one step in that direction.  To rest one turn, click Santa.

Keyboard Controls: press the arrow keys to move; you may press two keys at once (for example, Up+Right) to move diagonally.  To rest one turn, press the spacebar.

Melting Snow Goons: press H to melt adjacent snow goons with your warm heart and merry laugh!  But beware, you can only do this so many times.  Collect hearts on the field to replenish your supply.

The game is over when a snow goon catches Santa and gives him the chills.  How long can you last?
