Finally, I have prepared the long-awaited update of the program:
1) Updated the loading screen, added photos of the ruins, photos of the authors and the logo of our university and REC.
2) Significantly improved the on-screen joystick: fixed the sticks, added buttons for jumping, flying, calling the menu and exiting to the screen.
3) Improved and corrected the help screen: The resolution now is adjusted by a separate slider, quality - by a dropbox, app now correctly save your settings.
