This is a bug, It's been fixed now. Good job spotting this! Your run is phenomenal by the way. Cheers :)
Hey, I'm the Developer. Racingmonsters right. And adding replays is quite difficult, I'll consider it for the future though :)
I'm going to make a in-game bench marker, and i will be adding your best times for each level up in the stats menu (when its added), Then there will be two speedrun types, good suggestion! :)
