This speed run of the 2010 release was done spontaneously due to YouTube's new 15 minute video time limit allowing for a full playthrough of the game. A death near the end of the video causes an extra minute of play time, but the playthrough clocks in at about 14 minutes. Small edits to the game have been done since this run was recorded, so level layouts in the current release will differ slightly.
This video, a basic overview of how the game works, was made prior to the 2009 release.
