This is a two player game. One person uses the arrow keys to move and the other person uses wasd. If the color of the background is blue than the blue person chases the red person. If the color of the background is red than the red person chases the blue person. If you get tagged by the person chasing you than your score goes down by 1 and your opponents score goes up by 2. If you touch the blocks than you get pushed in the direction of the arrow.
This is a remix of Toms tag by TomTomJW7. I added a starter screen and cleaned up the code but the game is the same.
