PlayStation Portable developer slicer4ever visited the QJ.NET Forums earlier to announce the release of Pixel Attack v0.3. The biggest upgrade that's been added to this homebrew game is its MP3 support. Players can now load whatever tunes they've got stored in their MUSIC folder directly in the game. As for the rest of the changes to version 0.4 (quoting slicer4ever's post)

* added mp3 support directly from music folder
* added more background effects
* rainbow effect
* life ball(increases life)
* psp-hacks splash screen

slicer4ever notes that users will need the recently released 1.5 add-on for this game to run properly. Installation and usage details are available in the file bundle's readme. Those interested in further information regarding Pixel Attack v0.3 will want to visit slicer4ever's release thread at the QJ.NET PSP Development Forum.

Stick around guys - the dev's planning to add some interesting new features to this game's future versions, including online Hi-scores, Ad-Hoc multiplayer, and WLan multiplayer.
