this is the weirdest parkour run I've ever seen
You're right, I think that is better. I've been looking into the category extensions, and I have just one more proposal (for now): The full iron armor and 15 levels run is good and all, but why not add another category for full iron armor and 16 levels? I think that could be very fun.
Upon reading the replies to my original idea, I realize that not only does this already exist (albeit in a spot that isn't easy to find initially), but it also isn't quite as competitive as I was hoping it would be. I do, however, have a much better idea for a category. Sleep%, where players can compete to see who can sleep in Minecraft the fastest. Time stops as soon as your player wakes up. I think this one will attract a lot more players than death%, because some parents won't be okay with their kids willingly throwing themselves off cliffs in a video game.
I think there should be a death% category. I think it would be very competitive and would bring life to this already thriving community. I'm tired of mining for Mining a Chunk% and I want something quicker
