Alphawin

The defining escalation in Alphawin's Flappy is the shrinking pipe gap: every point scored tightens the opening you must pass through, turning the early game into practice for the real challenge ahead. At low scores, the gap is generous enough to flap through with loose timing; by the time you reach double digits, the gap demands that each flap brings your bird to almost exactly the right altitude. This escalation creates a natural difficulty curve within a single run, there's no level select or setting to adjust, the game itself becomes harder in real time as you improve. The golden pipe bonus every tenth pair provides a rare break in the tension: a special pipe that drops bonus coins while rewarding the skill it took to reach it. Flappy saves your best score and last ten runs locally, making your gap-survival progress easy to track with no sign-in required.
