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

Surprisingly, you have to sit on the opening screen for a second or so before starting every run to get the best speedrun cycle for level 3. So I would say also with fast resets, it would be enough marketing even in the speedrun lol. (Coming from someone has spent hours speedrunning it so far)

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 :)
