what i do is just aim at the little box that limcube talks about by either just holding zl when entering, or by throw aiming at it, but thing that took me a while to figure out is that instead of shield surfing normally, you need to press x and a at the same time to do an instant shield jump into the elevator.
one idea though would be to add a talus to kill%
If they make a ng+ category it'll probably blow up with runs immediately, so be prepared for hundreds of notifications.
I think there should be a speedrun of the sans fight where time starts on the last frame of heart blinking and ends when Chara hits sans. There could also be another category in it where it is the bad time simulator fight.
I agree with coolhandmike because the hardest games to get a wr on are ones that a bunch of people did and have optimized. However I think that one of the hardest games to speedrun is TLoZ BotW, because there are hundreds, maybe thousands of runners on different categories on that game. And even if there weren't, with the way the run is now, it took me over 100 hours of practice just to run plateau% at 44 minutes, and that's just half of any%. Yes, I'm not great at most video games, but Breath of the Wild is my one exception.
I want to have Bad time simulator added because there is no sans fight category in undertale, and even if there was, bad time sim. doesn't have text, so it is faster, and there can also be multiple categories, such as practice mode, normal mode, and maybe endless modes, or no healing/damage. Here is my run; https://drive.google.com/file/d/1Hc6HyAXMwKO9ePf16UWLPQSM8DqYS43E/view
