I know this is kind of out of place but I think a considerably big amount of people are forgetting the "Save Rating" button.
I just realized that my game has 367 plays and only 52 ratings. I think a lot of people forget pressing the "SAVE" button. I realized that I myself forgot twice too when I looked back on the comments I gave.
Then I saw Mark himself forgetting the save button during his stream. The audience had to warn him so he got back and re-rated the submission.
Can you make it so that on rating value change the rating is saved and remove the button.
