I turned on the spot since I thought the guard was done talking, and either it's an emulator glitch or frame perfect, but he's still talking about Sludge Bomb. I presume it's either well known or not useful enough to make a difference, but still not something I expected to be able to do!

some textboxes, typically final ones without arrows, you can clear with directions, pretty useful to save time by skipping turnframes but it is something we already do in runs
