Endless zoom
Pinch, drag or double-tap your way into the picture.
Zoom in. Then zoom in again.

Every picture hides a door to the next one: a frame, a window, a screen. Zoom deeper and deeper, and in the last scene find the golden acorn.
Pinch, drag or double-tap your way into the picture.
Hidden somewhere in the very last scene.
Easy, medium, hard and endless, with stars and hints.
The Plus editions have no advertisements at all, and on iPhone and iPad they bring Game Center leaderboards.
