Hi mates whats is the rate policy of the jam, some games has 0 rates and others 25, thats not fair at all.
I think that some parameters should be established so that all participants are obliged to vote, otherwise if anyone can interfere in the voting, there will be no votes according to the number of games.
Another option is as they do in other GameJams, only a jury votes in this way, they make sure that the votes are even for all the participants.
That beign said just rate my game if you like.
