Sans Fast Slam Attack Question

Question

In Bad Time Simulator section "sans_bonestab3", I used to be able to dodge consecutive slams against the same wall flawlessly. But after playing it over and over again in the past week, I can hardly ever dodge consecutive slams against the same wall.

Has this ever happened to anybody else, or is this something strange and unusual?

Answer 1

Lore-wise, you're not supposed to dodge that attack. Sans gets desperate and does an unavoidable attack, but Frisk/Chara powers through by sheer Determination.
