This is so hard ! Which may be a good thing because if it's too easy then you will just get into an endless grind.
I see you are a man of culture as well, using basic shapes and primary colors as I also have :D
An improvement would be an indication of which player you are yourself, because now I need to look at the score to see who I am on the leaderboard.
Also I don't think the leaderboard is updated directy as I got a score of 9 but this was not on the leaderboard:
Either way: Great job on submitting to the jam !
