Andorien has released his Breakout PSP version 0.1.
Breakout PSP is a PSP adoption of the classical Breakout.
The rule is simple, use the left/right on the d-pad/analog stick to move the paddle, use it to bounce the ball to prevent it from falling down to the bottom of the screen. Clear all the bricks to beat the game. The speed of the ball will increase when a brick is destroyed. The current version contains some problems with the collision handling, but hopefully the author will try to fix them in the next release.
