On Windows 8.1 I recommend volume 50 because the sound may sound too loud when volume is set to too large numbers. I changed the top score to World Top Score because Top Score was always saved for me at 15. Write in the comments and write what yours was saved on or if it actually worked all the time to go in and out of the game and have no problems.
Big thanks to my uncle Ariusz (arekc) for all good advice and tutorship.
