This, for me, had to be one of the toughest achievements in the game. Levels 1 & 2 weren't bad, but level 3 took me a considerable amount of time. The only real advice I can offer is to play the level enough times to learn the layout, then start trying to complete it as fast you can while collecting everything. As a side note, my best time before my lucky run-through of level 3 was 1:21. Timing and learning to aim are key here.
