Kills Time
Very entertaining for 5 minutes, this is something you could possibly adapt to have a prolonged entertainment factor. Did you base this off the German office chair racing, I saw it on the news a few weeks ago. Maybe you should add different characters, like the guy who dressed his chair like a horse. :) And maybe have different courses, like a race, and include tricks, seeing as they had bumps on their actual course. I was indeed bored when I played this, but now I'm bored again, so hopefully you can make something out of constructive criticisms. :)
