Cave flyer · no buttons
There is nothing to tap. The front camera watches your eyes, and every blink beats the bat's wings once. Stop blinking and you sink into the cave floor; blink too eagerly and you clip the ceiling. It is the least dignified way anyone has ever played a flying game, and it is extremely hard to put down.

Four lines. You will have read them before the first run ends.
One blink, one wingbeat. The detector ignores anything shorter than a real blink, so you cannot cheat it by squinting.
Gravity never stops. Holding altitude is a rhythm, not a state, and your eyes get tired exactly when the cave gets narrow.
The cave closes in from above and below in uneven ridges. There is no safe altitude, only a safe moment.
You are not the only thing in here. Enemy bats cross your line at their own pace and do not care about your high score.
Each difficulty keeps its own global leaderboard, so an Easy record never sits next to a Hard one.
A wide cave and a forgiving flap. Where everyone learns that blinking on purpose is weirdly difficult.
The intended game. Tight enough to punish a lazy blink, open enough that a good run feels earned.
For people whose eyelids have become athletic. Bring eye drops.
Sign in with Google, pick a username, and your best score per difficulty goes on the board. Choose your bat's colour while you are in Settings — and delete your account from the same screen whenever you like.
A game that watches your face owes you a straight answer about what it does with the footage.
Winky Bat uses Apple's on-device face detection to answer one question, frame by frame: are the eyes open or closed? That answer is the only thing the game receives.
No frame is recorded, saved, or uploaded. There is no video file, no face print, and nothing sent to a server. The camera runs only while a round is in progress, and iOS shows its indicator the entire time.
What does leave the device is what you would expect: your username and your scores, so the leaderboard can exist.
Blink detection is only as good as the picture. A dark room or a face half in shadow makes the bat unresponsive, and that is the game's fault, not yours.
Playing requires camera permission and a signed-in username. You can skip sign-in to look around, but a round will not start until you have one.
A full-screen ad appears between runs. That is how a free game with a global leaderboard pays for itself.
Nor will lying down, nor filming yourself in a moving car. Sit up, face the phone, and blink like you mean it.
