The world changing screen on the main menu seems to be the same one from the desktop version and thus is almost impossible to use on smaller devices. The sorting options on the top of the screens click boxes are also too small to be tapped on as the arrows are tiny. While the worlds themselves can be tapped on most of the time a mistap will occur as they are also very small. Annoyingly this will take you out of the screen and back into the main menu where you will have to try again. Could more of the blank space in the menu be utilised to make the screen easier to use or a scroll bar be added so larger buttons can be displayed at once?
