Hello Cho I return because I took another replay through the game recently and I think you'd enjoy my tale of the unintentional bonus pinch of pain I experienced when I decided to finally tackle the No Love route. Posting it down here instead of in a new comment to hide it better, but just in case!
!!! SPOILERS !!!
For No Love route I changed the name (because on some level I am still a weenie), and the thing is. When I did this. I managed to skip over Flowey's whole barb about it in the beginning. So I went through the ENTIRE ROUTE having no idea that it hadn't truly mattered, which made Sans saying the first name I input instead of the name I put in for that specific playthrough at the end hit WAY HARDER sdhgfjsdg
It truly was the most karmic of punishments and I'm laughing thinking about it even now!!
