PolygonCeption - Need Help

Ok, at this point I am reverting to the original strategy, but it still won’t work. Also, I believe that there is a problem with the actual level, seeing as everything is executed properly, but nothing actually happens.
Here is my code:

# You can find friends through walls, but not enemies.
# Watch out for smooth, frictionless ice patches!
hero.moveXY(68, 16)
def killThemAll(friends):
    for friend in friends:
        enemy = friend.findNearestEnemy()
        if enemy.type == "witch":
            hero.command(friend, "attack", witch)
        elif enemy:
            hero.command(friend, "attack", enemy)
while True:
    friends = hero.findFriends()
    enemy1 = hero.findNearestEnemy()
    enemyMissile = hero.findNearest(hero.findEnemyMissiles())
    killThemAll(friends)
    if enemyMissile and hero.distanceTo(enemyMissile) < 5:
        if hero.isReady("shield"):
            hero.shield()
        else:
            hero.moveXY(12, 12)
    if enemy1 and enemy1.type == "catapult":
        hero.attack(enemy1)
    elif enemy1 > 20:
        hero.attack(enemy1)
    else:
        hero.moveXY(77, 14)
