Hello. I've recently been doing small fun runs on the "Genocide" category of this game, and have discovered small things.

1. Every single attack is completely scripted, and has a timer you can count from the very start of the attack. As soon as the attack "ends" and the battle box starts shrinking, you can hit z+enter at the same time to activate the "fight" box. Since the battle box is still growing back to normal size, the "fight" bar will start more near the middle. This allows you to attack enemies much quicker, and not miss out on any damage. There is a level of randomness to this trick, entirely based on how early or late you hit z+enter. It's something to mess around with (if anyone other than me plays this demo lol)

2. In the "Genocide" route, for whatever reason, Napstablook is NOT a required "kill" for the genocide ending. Sparing Napstablook is faster, and does not take you out of the run at all. This video is a small proof of it, a sped up run from the beginning, to the final save point that proves this to be true:

Those are all of my discoveries for now... and I don't even know if they're exactly discoveries! But I didn't see anyone actively using this in any category, so I thought i'd make the forum! A "wr" in the "Genocide" category will be submitted soon after this, which uses the Early Fight Box (EFB**™**) and Napstablook Kill Skip. If any mod who eventually verifies or rejects it has any questions or issues with the run, please leave a note when you verify/reject!

Thanks! - MyntiFresh
