Domain for this game has been created 9 days ago. So, i think someone was heavily inspired by my idea.
I understand that anyone can make game with same idea, but i'm bit sad that Enlinko haven't got such traction on HN as this game.
As for relatedness, my game uses semantic vectors from this model https://github.com/commonsense/conceptnet-numberbatch
