Started a new game and named my character "Frisk"鈥攊nstantly regretted it when Toriel's Ruins got way harder. So worth it though!
Just name your character "Frisk" at the start of the game to activate Hard Mode, which is considered serious mode. Easy peasy!
Pro tip: If you really want to keep it chill, don't name your character "Frisk"鈥攕eriously, you don't want those extra challenges!
