Here comes a PSP homebrew game from Arkanist: Box Killer v0.7. Though it may be Spanish, the gameplay is pretty simple. As you may gather from the name of the game, all you gotta do is kill all those boxes flying at your character on screen.

The game allows you to choose between four difficulty settings, and even has a tutorial. Here are the controls:

In the menu

* X: To accept/To enter.
* Digital DAP arrives Down/: We move by the menu.

In the game

* Or: To shoot.
* Digital DAP: Movement of the player.
* Trigger L: To slow down the game.
* Trigger R: To resume the game.
