ArrowSnapReact is a fast response game built around cardinal directions. A prompt for Up, Down, Left, or Right appears in the center, and you tap the matching button below before time runs out. Wrong direction or timeout counts as a mistake, and three mistakes end the run. As your score rises, prompt windows shrink and switches come more quickly, leaving less room to hesitate. Read the cue every round, avoid muscle-memory taps from the previous prompt, and answer cleanly under mounting time pressure. It rewards immediate mapping from cue to button as pace keeps accelerating.
