If you've already played Treasure Island Dizzy, based on the original 1987 game Dizzy by Codemasters or the virtual crossword game X word, then you're already familiar with Shallan's impressive resume.

Here's another PSP flash game from him called Portaball. Playing around it for while gave me a quick impression that it is a clone of the classic Breakout game, where you bounce the ball using a paddle to prevent it from falling and in turn bashing all the bricks above it.

Having studied some flash myself, I know that making this one is not that easy. Well, after all the game is not entirely graphics-based so I guess just a little tweak here and there will make this game better than its already-cool state. Overall, I think that it's a pretty decent flash game for your PSP.
