You play a scientist who's just discovered a virus that will wipe out humanity in six days, and every single choice you make sticks. One Chance drops you into a quiet apocalypse where you wander your lab, your home, and the empty streets, deciding how to spend whatever time is left. You walk left and right, interact with people and objects, and watch the world react to what you do, because there's no undo button and no second run. Save your family, chase a cure, or just sit with your daughter on a park bench while the clock runs out. The catch is right there in the name: you only get One Chance unblocked by any reset, so what will you choose?
How to Play & Controls
- Move: Left Arrow / A and Right Arrow / D
- Interact / talk / pick up: Spacebar or Up Arow / W
- Progress dialogue: Spacebar
Tips & Tricks
- Splitting your days between cure research and family changes the ending you reach, so decide early what matters.
- Talk to every coworker and stranger you pass, since their reactions hint at how the city is faling apart.
- Once a day ends you can't replay it, so think before you walk through that final door each morning.
