17 seconds? Yea, that’s right, think fast. There are a ton of +5′s locked in that you will need to nab to keep this level going and you need to move fast. Unlock all the ones you can to keep the level moving. There are 2 color bombs frozen in the bottom left and right corners to help you with the scoring though. Note that the clock will NOT go past 17 no matter how many you use. Remember the +5′s turn into wrapped candies and explode at the end of the level.
