Hello everyone!
I've been keeping an eye on the Undertale speedrunning scene and a
whole bunch of new glitches were discovered very recently! Most importantly, using the item 'Punch Card' with perfect precision allows for dialogue/cutscene skips, OOB tricks, and even mild wrong warping.
With this discovery, a pure neutral run will be much faster than a genocide, and it should be easy to complete the game in under an hour. We still don't know how many time saving wrong warps are possible. In the best case scenario, this would make for an extremely cool tas where Frisk is ignoring everyone left right and center while teleporting all over the place
It's a shame that we still lack the software to do it, because it's all there conceptually.
