So, here's an absolutely wild and crazy idea.
Instead of discussing the same tired points about human speed city block level Undertale that I've debunked literally over a dozen times, why don't we take the Napstablook calc (which objectively does not use any type of calc stacking whatsoever), check up on it to make sure all the math is solid/make any tweaks that need to be made, and apply that, instead?
Also going to note that unlike the Papyrus calc (which only directly scales to everyone Waterfall and onwards, the Napstablook calc applies to everyone after the Ruins (90% of everyone in the game), meaning we don't have to guess for everyone lower than Papyrus level. It also pretty much puts everyone back at levels similar to what I had them at originally and only uses one feat performed by one low-tier character.
If there are legitimate complaints with this (that I haven't already covered numerous times), then I would like to hear them, but to me, this seems like the best idea. Thoughts?
