I have rated more than 15 games but the queue keeps changing and I cannot complete it. It's sad because I cannot rate the games I prefer to rate - to give support.

Please advise.

at 25 games it allows you to rate whomever you want.

Ah, I see. Nudging me into ever more reviews! :D 5, 15, 25... 74? Maybe I will beat my personal record.

This is the first jam I'm participating in that asks participants how many games they can rate. And I think the amount of ratings is higher than the average jam. 

Is there a correlation? I believe so - because when asked openly about it people commit to it => they put more effort. Well done! I think it is useful for everyone.

Ah what a nice comment. Thanks for the positive input!
