Also with the game zip folder you were almost there so close. You just had to make it an html 5 game and make it 'In browser playable' when you upload it, then it automatically creates the Run game button. Good luck next
I really thank you so much for your help, by informing me about this issue, fortunately, I was able to change it from only downloadable to HTML browser, thank you for your kind help, and good luck for your game
