To pass this level, you need to use lots of boosters and booster combos.

1. First, you should do what you can to clear the area in the bottom right corner with rocket firecrackers or big firecrackers. Not only does this area have a lot of floor tiles, but it’s a more efficient way to clear the harps.

2. At the same time, don't forget buttons in other areas. There will be some floor tiles remaining in these places, and they should be cleared by using bomb combos to pass this level efficiently.
