hard Target: 18 moves 5 colors

Explode the upper-right crown, dump it onto the middle, and sweep the long curtain in 18 shots.

If the player asks you to sign in, open the video on YouTube instead.

Fire into the upper-right cluster around the pinwheel/firework and the silver pillar.
Follow with another shot on that same right shoulder so the right tower and nearby speaker block tumble into the center.
Let the crown settle, then break the remaining middle orange barrels and purple caps still holding the top rack over the curtain.
Once the upper weight is gone, start shaving the lower curtain from the right side where the debris already opened a lane.
Sweep left across the shortened orange-and-purple cylinder wall, leaving the far-left corner for last.
Finish the last purple cup and the stubby edge stack on the platform with 8 balls left.

Colors in this level:

Orange, Purple, Silver, White, Blue

Starting on the lower curtain before the upper-right crown has broken.
Ignoring the upper-right firework knot and trying to chip the whole crown evenly.

Use the upper-right firework cluster as the opener.
Let the speaker block and top tower crash into the middle before sweeping the curtain.
Leave the far-left corner of the lower curtain for late cleanup.

Board notes 5 details

Layout: A long lower curtain of orange and purple cylinders supports a smaller crown made of silver-white pillars, purple cups, orange barrels, square blue speaker blocks, and a pinwheel-like firework cluster on the upper-right shoulder.
Goal: Collapse the upper-right crown so the heavy top pieces crush the middle, then shave down the lower curtain until the last purple cup and stubby edge stack are gone.
Opening: Fire into the upper-right firework cluster beside the silver pillar instead of starting on the long lower curtain.
Danger Zone: The lower curtain is an ammo trap at the start, and the crown stays locked together if the upper-right firework knot is ignored.
Mechanics: A crown-explosion board over a long curtain base where the right shoulder has to break before the lower wall becomes cheap enough to clear.
