yes, I agree that downloadable type game like ours will get review less than the browser one since the browser take less effort to play and we need to rate many game. It is a problem not only in this jam but also the problem in my previous jam. The thing that work for me is, if you rate 50 game, you will get half of the rating which is 25. I also do that in my previous jam and now I also do that. I rated 100 game and now get 50 rating. Especially for unreal user like us, where the game size will be far bigger than others. we should expect lesser rating from there, so I think we need to do many-many more rating than other dev's do if we want to get rated. at least that what I think :D.
