[Timber Guard] Soldiers Too slow

Level Help
1

Hi everyone,
I’m looking for some help on level Timber Guard.
My soldiers are not moving fast enough to defeat the first wave of enemies to protect the peasants.
I have changed my code for my hero to collect the most valuable coins to generate soldiers faster, but still not working.

def findBestCoin():
    worth = 0
    bestCoin = None
    coins = hero.findItems()
    for coin in coins:
        if coin.value / hero.distanceTo(coin) > worth:
            worth = coin.value / hero.distanceTo(coin)
            bestCoin = coin
    return bestCoin


while True:
    bestCoin = findBestCoin()
    
    if bestCoin:
        hero.moveXY(bestCoin.pos.x, bestCoin.pos.y)
    # If you have enough gold, summon a soldier.
    if hero.gold > hero.costOf("soldier"):
        hero.summon("soldier")
    # Use a for-loop to command each soldier.
    # For loops have two parts: "for X in Y"
    # Y is the array to loop over.
    # The loop will run once for each item in Y, with X set to the current item.
    for friend in hero.findFriends():
        
        if friend.type == "soldier":
            enemy = friend.findNearestEnemy()
            if (enemy):
                hero.command(friend, "attack", enemy)
            else:
                hero.command(friend, "move", {'x': 69, 'y': 42})
