Always a hair's breadth from destruction, you have to watch both circles at once. Walls approach on both sides of the screen but with different timing, so steer the circles to safety for as long as you can!
Something happens when you reach a certain point in the game...
The controls are simple! Swipe vertically to move the circles on the left and right sides of the screen. If you hit a wall, it is game over! Steer both circles at once and see how far you can go!
