Type the flowing text to add floors to your building, one at a time. Fill a building and a new one rises beside it — your skyline keeps growing across every session you play, even after you come back days later. Mistakes pile up risk: cross the threshold and an emergency breaks out, flashing a word you must type before the timer runs out, or the building takes damage. In Endurance, a failed emergency also costs a life — lose all three and it's over. In Zen, there are no lives, just a 3-minute clock.
