the purpose of the game was to force marketing upon the players. a speed run version would defeat the dwell time of the marketing on the screen. i'm sure the marketing department would not be a fan

Perhaps make it such that once you've completed it at 'normal' speed all the marketing messages are disabled, enabling the speedrun.

For what it's worth our head of marketing was the one asking for a speedrun mode, but it just couldn't make the cut in terms of scope :)
