Snake 2 by Chris Grayson, Christine Duong, Ethan Edgerton.

Release notes:

Two opposing players separated by a line that runs vertically down the middle of the play space. On each side of the play space, there is also a wall that further restricts the movement of each player. If either player runs into their back wall or the “fence” in the middle, they will lose a life, which is documented on the score counter, and then be transported back to the middle of their area.
