If you have five spare minutes, Falcon Dive will fill them. Everything happens on one screen with gaps that start at 30% of the screen and shrink with every point, and the whole thing runs straight in the browser - no downloads, no sign-ups, no fuss.
Scoring is per pipe, and the difficulty comes from variety - gap heights drift up and down the screen, so no two pipes arrive the same way. The ramp is honest: nothing suddenly teleports, the world just stops forgiving lazy taps.
The loop is deliberately compact: one round takes minutes, improvement is visible, and the next run is one tap away. That makes it a reliable filler for short breaks - and an easy game to recommend to someone who 'does not really play games'.
