He was the one making a demo so you could TRY the game, and see if you want to buy it. It's not like anyone is forcing him to making a demo, and he's only being nice for doing it, so what the hell is the point in giving few stars only because it's short? That's like giving an awesome retail game a 1/5 because you played the demo and didn't like the fact it was short....
