It really is bold that it seems like you've decided to make Genocide your first run. I find it really fun because I've done that ending first, too =D It really is a unique experience to do a blind Genocide as a first run, different to one people have when doing Pacifist/Neutral first. Your view of the characters really does change when you do another endings later, so I encourage you to stay on the chosen path and beat Genocide before any other route :P There will be quite a few obstacles in your way, try not to spoil everything (it's REALLY simple to do so). Save the 30HP+ heals, sorry for the advice but you WILL need them, judging by your skills with the game, haha. And, most of all, I wish you luck on your painful, yet fruitful journey xD
She is actually easy. I have no clue how you managed to reach her with such awful heal items. With your reaction speed i dont think you gonna beat next genocide bosses without spending 10 hours on each
Yea that's part of the joke. Separated from the fact of the genocide route being much more difficult and that I've seen the consensus is that this fight is blindsidingly hard during my research (also other commenters have said it), I'm over here saying I'm getting better and get destroyed by an early boss. I will defeat all of the bosses, don't you worry about that :P
