if you faced the standard undyne, heck, if monster kid tried to be your friend instead of being scared of you, then you probably did it wrong.

a couple of things to make sure when you are doing a genocide run:

''1. in the ruins, the kill count doesn't show, ever. this means you have no end goal killing everyone, and is really just a message out of nowhere that starts the genocide run. kill everyone.''

''2. in 'Snowdin', it starts to show the counter. 'I' guess it did for you if you killed everyone in the ruins. you need to kill certain one of a kind enemies like 'snowdrake', 'doggo', maybe lesser dog etc.''

3. in waterfall, if there is no kill count, you screwed something up in snowdin. if there is, exhaust away. no special encounters here.

verdict: from what 'I' can get here, the two most likely things that happened are:

A: you didn't kill everybody in the ruins and get "but nobody came."

B: you missed a special encounter/kill in 'snowdin'.

if you did any of those, fail. if you didn't do any of them, then I don't know either lol.

but yeah. that might solve it.good luck next time :)
