A game built with HTML5 / jQuery where you alternate between branching and merging.
You can play it here.
Change your direction using the WASD/Arrow keys.
You initially branch by touching a green tile and then merge afterwards by touching a red tile. Repeating this process will gradually increase your movement speed.
Failure to alternate between branching and merging will result in a game over. Hitting a wall also results in a game over.
