There's o magic formula, I'm afraid. if you can stock up on lollipops and jelly hands in advance (there are ways to do that without it costing you anything) that will at least give you the opportunity to take out a bomb that you can't otherwise reach.
Hi. I was able to clear it working from the bottom. The cascade effect helped me tons. I think I might ve used a lollipop or two, but what worked for me was the cascade effect. Good luck.
