Heh, well, you got the pong sounds down pretty well. The music, well, felt a bit like pirate ship music to me? :P I just feel like a pong game such as this needs more happy, fun music. But maybe that's just me.
For a pong game, I mean, it's pretty much standard. I do find it odd that when the ball hits the paddle while moving, it can send the ball into an almost perfect horizontal line, rebounding between the two walls. It takes a long time not because the ball is bouncing around other blocks, but sometimes just because of this very gradual upwards movement that can take quite a while before it actually reaches the blocks!
The graphics feel very retro, which is neat. I like how the island is the paddle. But what does that make the ball, then? And why would the ball constantly hit the island? :P
