This game was a cool idea and I think your execution was good. Something memorable is usually games like this are very luck base. You added paddles to move the ball in order to remedy this. To improve you definitely need some ui elements. Especially a scoring system. I would also add some more visual flare or sound effects to make it more juicy. This game seems to be themed like a casino style game so maybe add some casino visual elements. This would make it a lot more addicting. Thats the whole point of casinos is to get people hooked. The balls move a little fast I think it would be good to slow them down. The execution if this game is successful. The physics work great and nothing is broken. I just feel like the big thing that is missing is a visual theme.
