The gameplay of The Legend of Zelda: Majora’s Mask is famously limited to three days. After three days the moon crashes into the town, destroying it. You have to go back in time before then (which also saves the game) and continue completing subquests in a non-linear, atemporal kind of way.
But as it turns out, there is a way around it, which puts the game into a sort of limbo. People who would ordinarily be moving around on their schedules are completely missing. Entering into some buildings crashes the game. In any event you’re stuck until you finally play the Song of Time and reset the world, getting events back on track.
