About game

Frisk has fallen into a spiralling madness, repeatedly triggering Undertale's dire conclusion. Only Sans, aided by Gaster, can break this endless loop of chaos. This is the opening phase of a trial that tests Sans's skills to the limit. You must evade his diverse barrage of bone assaults. Struggling? Train in a simpler mode without karma or opt for the single-attack option. Your mission: withstand Sans's onslaught and emerge victorious.

How to play
