Smiley Math Integers

Help Smiley clear the board by finding and collecting the negative and positive integers that help you come up with the required total.  No time limit but you'll need to stay on the move to avoid the monster.

Click or tap a space horizontally or vertically adjacent to Smiley.  These locations are highlighted in yellow.  Once you've moved Smiley over an integer you want, just click or tap Smiley.  To complete a level keep collecting the correct answers until the board is cleared.  You'll lose a life if the monster gets Smiley.  You'll also lose a life if you go over the requested positive total or under a requested negative total.
