Bascially, yes.
This is of course only opinion from a gamer. But my perspective is how to find games. I have deactivtated auto play for web games, so no screens and too short description are bad. And to even go to the game page, I might have seen the game in browse, but not hover screenshots give no information. I also would not have found them via shared tags from other games I visited. I am not sure, if I used horrible correctly, but it sounds nice to mean that a thing is not good. As in, could be better compared to others trying to do the same thing.
I would liken it to writing a book. And then the writer doodles a stick figure as the cover image. Unless your last name is Munroe, that is a bad idea ;-)
