The full screen button at the lower right corner overlays on top of the end of the slider, making it impossible to click to set the slider button there, or if I slide the slider button all the way there, then I can't drag it to a different position without triggering the full-screen. When in full screen, the right side of the game got cropped off.
Like the other commented, there were times I clicked through the whole slider and still could not find the station.
Is the game about clicking through the slider fast enough plus with some luck to find that secret position before time's up?
