i totally want to change the ui, In my first, the theme are shown only start of the game if once start the game user cannot change the theme,user can change only after refresh , so i add settings button and history button ,in history log user can view his history of play with time ,score,coins he earned,in setting user can change the theme,mode(difficulty) ,and he can delete the history and can restart the game ,on deleting the history only history log deletes the coins he earn and best score not deleted ,on restart the game it totally deletes everything like coins he earned,and best score and also history,once game started the coins details and settings,history isons are hided and after game over in restart popup i added back button to go to lobby so user can again change setting instead of refreshing it , now i just make the ui for that i will write js soon, it take very long time to think i aging and aging change the code to get this ui
