Super Stardust HD

Start on easy mode on the first planet and every time you see a shield token collect it. If you see a ship token, don't take it for a few seconds and wait for it to turn to a shield, then pick it up. This is not a consecutive Trophy but it appears you must do it on the same life. So if you lose your shield, you still have a shot at the Trophy, just pick up another shield and carry on collecting them. Might be worth attempting this while going for the gold Trophy, "Multiplier Hero".
