Theres no timelimit so this makes the search very relaxing. Additionally I actually really like the controls, despite all the complaints. Hint: when youre zooming in, just click a found object once - then tap once on another part of the screen, you can even do this while dragging - the object will move there and will keep on hanging in the air. You can now drag the screen up to where youre supposed to drop the object. Tap a second time and the object will drop.
