Don't know what to speedrun :(
Also on mine I suspect that an estimate of 2:30 is going to be quite high for Muramasa. I'm getting down into the high 1:40's on easy mode. I suppose you could leave it that high if we want to do donations for hard mode but I hope by the marathon I can finish even hard mode under 2 hours consistently. So you might want to update Muramasa to 2 hours.
