Start three clicks to the left and destroy the single brick that’s touching the left wall, and when the ball returns, hit it with the left side of your paddle to send it back up the left wall and dislodge the capsule directly above. Keep shooting for this brick until you have destroyed it and cleared out a path to the top of the level along the left wall. When the ball is no longer moving fast, clear out the two bricks touching the right wall, giving yourself an additional escape route. Then, work on destroying the bricks on the left half of the board, where most of the capsules are hidden. Finally, clear out the right half of the board.
If you get the Laser or Gun at any point, first make sure you’ve cleared out both chutes on the left and right, then clear out as many bricks as you can on the bottom half of the board so that you have some breathing room.
