to reset simply refresh the page, 48 hours was a slit exaggeration, but the amount of time I put into these games was unreal. After I had finished them, I was too lazy and still am too lazy to add any other features. to answer your HTML question, HTML is used to structure websites, what I used to create the game was actually Javascript. When these languages are combined(along with some others) it is known as HTML5. Javascript is not hard to learn and it is very simple to work with
