Go to level 12-3 and shoot the first to speed shot to clear the closest wall facing you, and just waste the second. Now that you just have your lift shots left, shoot them at lower power aiming toward the now destroyed wall and activate it after less than a second for your first Daredevil bonus. Activate it again as it starts to arc downward to clear the gap. Finally activate it a third time right before it hits the ground for your second Daredevil bonus. Repeat with Lift Shot #2 for 4 bonuses per play of this level. Rinse and repeat until you have a cumulative number of 20 "Daredevil" icons.
