Good point. I've tested and all the levels are beatable eventually, although some are quite long and difficult. The ball gains some speed with each hit, so eventually it will have the kinetic energy to overcome the potential and behave like classical Pong. If I create a more polished version of this, I will likely design the potentials manually; here I was rather lazy in making this proof-of-concept demo so I generated all the levels randomly.
