At the very bottom of the screen, you will see a circle and an arrow. Which is constantly turning. By pressing, you will fix the direction you need, with the second press you will release the circle so that it hooks on the round platform. Watch the filling of the arrow, the fuller it is, the further the flight will be. Getting into a large platform is not so difficult, it is much more difficult to get into a small or very small one in Reach the Platform.
