2048 Runner

You must make your way past a series of gates and cubes, steering clear of the negative ones and instead entering the positive gates and combining with the same cube. You should not join with the cubes with a different number. You must make it to the end of the level with a figure that is at least equal to the assigned goal. With quick reactions and clever tactics, you must stay one step ahead of the negative gates to get through each level and ultimately be victorious.
