My suggestions:

Papyrus's puzzles actually work.

Both Toriel and Asgore don't take it easy on you when you fight them.

Mettaton NEO doesn't go down in one hit and his attacks are extremely devastating.

Omega/Photoshop Flowey doesn't use any checkpoints and the soul parts can actually kill you.

Alphys doesn't give you the answers during Mettaton's quiz.

The tiny spider doesn't show what attacks Muffet is going to use next during her fight.

In Genocide, there's another boss fight after Sans in which the scenario could be either Asgore absorbing the 6 human souls or Flowey betraying you. Either way, they're even more tougher to beat than Sans is.

And finally...You can't ditch Jerry.
