In a world where time can be manipulated, you play as a quirky history teacher named Tessa Timelock who accidentally stumbles upon a magical hourglass that grants her wild control over time. Instead of escaping confinement or dealing with stranded islanders, Tessa must navigate time periods gone awry, fixing humorous and chaotic anomalies caused by her rambunctious group of students—her 'chrono-chums.' Each student has something unique about them that interacts with history: a prankster who sends medieval knights into a dance-off, a science geek who accidentally invents steam-powered beepers, and an artist who decides to change famous paintings forever. It's Tessa's job to guide them through historical events, choosing dialogue and actions that impact the outcome. Will she restore history or have a good chuckle as her students turn it upside down? It's a race against time, with laughter and excitement at every turn.
