I was wondering why there were long black screens in the game... Ads, with a good ad blocker. Now I know. -2 points.
Quite an easy game, maybe some questions should not be repeated until the good answer is found, and there is an ambiguity on the Back To The Future question (same digits should go anywhere, screw the little dots on the bottom right corner !). -0,5 point.
Plus, I got three stars although I made a lot of mistakes. It does not seem fair. -0,25 point.
I will round it down to 2/5.
