I'm sorry to hear that you went through the trouble of downloading it without knowing that it requires a controller. I hope that maybe you'll be able to revisit later with the right hardware.
But, by the more information page, are you referring to the actual game page? I was under the impression that this submission page is more of a short blurb for the contest runners' sake. It doesn't even have a form on it for instructions after all. As to the actual game page, the controller requirement is actually before the "more information" cutoff, so I am unsure of what you are recommending that I change.
If you are able to play it later, I do hope you'll pass on your feedback!
