About game

Engage in battle with Sans from the Underswap world! In this universe, characters from Undertale have undergone a role reversal, and Papyrus and Sans are prime examples. Unlike the original, it's now Sans who is the younger brother with big aspirations, though their personalities remain familiar. Sans seeks a fair fight, just for enjoyment 😉. You have the option to show mercy, which might lead to an alternative conclusion to the battle! Enjoy your game!
