I did this run today, and I'm surprised about how lucky I was! I messed up the Topaz so bad, I was about to reset. But I figured I might as well give it a shot, because it's not like this would be the run where I get insane Goblin Scout luck, right? Well, now my failure is here for everyone to see. The rest of the run was pretty good, I believe that my idea of Grenades to Spiky Balls then back to Grenades at the end is the best strategy.
This is such a weird category, because despite being a short, 1.3 Glitched category, almost no one ever ran it. Over the course of more than 5 years, only 6 unique runners ever did this category, and the last record was set by Yui in November 2018, 3 and a half years ago. I was a freshman when that run was done! It's quite cool to beat a record that old, even if it wasn't a huge challenge due to modern strategies and seeds.
