I was wondering if there's going to be a highscore category for mercenaries.

I just uploaded a Challenge 1 run and had to choose a difficulty eventhough there is no selectable difficulty for the challenges. What would be the correct way to go about it ? I just picked casual difficulty.

Also wonder what's up with the leaderboard because there's a 0.00.01 run in first place which isn't even possible. :)
