Mad Mew Mew% on switch. You can enter the mad mew mew door after exiting the mettaton EX room. Time ends either when you spare mad mew mew, or when you land a killing blow on her. Not everyone owns Undertale on their switch, but it would be an interesting category.

The only other suggestion I have is chapter 2 NG+. Start chapter 2 from a completed chapter 1 file. You are allowed to have anything from chapter 1 that may benefit you. The only major timesaves would be the werewire battle, the Rules fight, and the queen fight.

What about Hacker percent? Trigger the hacker fireworks cutscenes as fast as possible.

all weapons% complete both chapters while obtaining every weapon.

Weapons:

Spooky Sword Ragger Dainty Scarf Brave Axe Devil's Knife Fiber scarf Mecha Saber Auto Axe Ragger 2 Freeze Ring Thorn Ring Bounce Blade Puppet Scarf

potassium% would be different from any% though. Just get to the door in cyber field and warp to the trash zone, than play as if its any% nmg until the second banana. An optimized run would be a bit over 30 minutes long.

Jaq is at it again. Doing another record sweep.

Oh my god. Ash finally did it! He fianlly beat nharr's record that stood for over a year! The new 1.09 wr is a 26:04, which means chapter 1 runs are back! (Maybe)

Bro this has to be the longest standing world record that exists in deltarune. Ashmichda and ThemagicD seem to be closing in on this wr, so I'm excited to see what happens.
