That was an interesting idea, haven't quite seen something like that.
I was going to say don't look down on 7 ratings but now you are 12 so well done on that.
Regardless ratings are not everything it is about the quality of ratings. I know I will be saying that sentence a few times in this forum because a couple of games after you mentioned their ratings.
Still your game was good quality you will still get a decent ranking from the number of ratings, it is based on your average score rather than your total votes, or something like that from what I can see with previous GMTK ranks.
