There's no comment section on the game page, so I'll post it here. I don't think there's any critique in a pong game so I'll skip that and leave you with these few short thoughts. Please do not obstruct the game field/area especially in pong. The particles on the ball cloud the game area depending on its speed thus I am not able to instantly discern where the ball is supposed to go, plus the paddles are also made of particles, so an easy ball can be a missed one due to misleading length. Barrier adds a very slight random level to gameplay. I've also noticed that the ball comes towards you faster/slowly depending if you hold a point advantage or disadvantage, at least that's something rewarding for the player other than the art.
