Would you consider this flirting? Was he conveying that he wants me?

I was joking about what he said. I told him that I would give him red card for that  ( red card is from soccer/football where the referee will give player a red card for a serious offend)

He replied: haha well that means that the game is over then  ( the emoji he used was the distraught face emoji)
