I mean you cant get an original art style, because there are thousands of games, and your bound to have the same with at least one, it called a demo, I know you want the game to be good, but he has to do things one at a time, when you say "you can't take shortcuts with ugly design, it's your dream game!" he has to make the basic controls first, and not focus on things like looks, he has to make sure the game feels good before looking good
