As this is merely a test the game isnt as polished as it could be nor will it ever be but its really quite playable even if the collision is a little "spongy". Ive added some music I made for it and a few powerups to make it more of a game. There are 8 levels which repeat once you complete them and 6 powerups. You can find it and more at my site here

As you can see the game is played from the side so best to hold the PSP this way. Use analog stick to control the bat and X button to start the game and launch a "caught" ball once you have this powerup.
Should anyone find game stopping bugs, I may tidy them up but for now the game is staying as is, Enjoy!
