Undyne is harder.

Why?

I always died during the red-heart-spinning-circles part, because maybe Aicilespear is right about Undyne being pure skilled while Sans only pure memory. Wait a second? If Undyne is pure skill and Sans is pure memory, then how the heck did you beat Sans in one try? His attacks are meant to be fast and unpredictable until getting the feel of it. It is almost impossible to beat them on the first try because of this. You are meant to be dead after the surprise 1st attack, and if not that, then the blue attacks that come 2 turns after..

I can assume you prepared by watching youtube videos amirite :P
