We have almost 500 submissions and still 4 hours until closing  time.

THAT'S A LOT OF GAMES.

So from this (European) evening on I pledge to play at least 3 random games per day and each one for at least 15 minutes. If everybody does  that we'd get together 50-150 ratings per game (assuming that teams have 2-4 members).

What else can we do to get more attention?

That is a tall task for sure.

I'll try to do the same. Someone has to play these games for them to be rated y'know.

i'll try also to play and rate a lot of games because i know the effort and time that all the teams spent including mine.

I hope my game likes to everybody! 

I'll try to do the same!
Making a game isn't easy and people deserve some feedback
