Developer coolguy5678, also the creator of the Unofficial CSPSP Editor, visited the QJ.NET Forums earlier to announce the release of 4². As its name implies, this homebrew is a PSP port of the popular Four Square ball game some of you may remember playing.

There are four players to this game, with each getting assigned a square. Your objective to try to hit a ball as soon as it bounces once on your square into the square of another player. If you make a mistake, you're out, and the player from a lower square than you moves up to take your place. A new player than takes the bottom-ranking square.

The highest ranking square is the king square, which is located on the top left of the screen. You'll be playing as a blue player, and you'll actually earn double points if you managed to fight your way to the top two squares. As for 4^2's controls:

* Use the analog/or d-pad to move.
* Hold X to charge up your shot.
* Release X when the ball is near you to hit it.

The ball will travel in the direction your player's cone is pointed. Timing your charge is important, as releasing X while the ball is still far from your sprite will cause it to travel much slower.

Further details on controls and the game rules are available in the file bundle's readme. You may also want to visit coolguy5678's release thread at the QJ.NET PSP Development Forum if you're interested in posting your feedback.
