Some friends on a website were trying to beat this level in bonus mode but kept failing. (The pieces come in random order.) So I decided to steal their glory by attempting it myself. ;)
You may notice that I turned on "MouseKeys" (an Accessibility feature in WinXP) to use my keyboard's numpad to control my cursor with pixel-perfect precision.
Nothing happens in the period from 65 to 125 game-seconds. During this time I was contemplating suicide, thinking I wouldn't be able to pull this off because the small horizontal bar ruined my original plan. I also tried to stick the horizontal bar in-between two existing pieces, but the game would have none of it.
