From the developer's of Ackby's Breakout:
In celebration of the New Year I have decided to whip up a new level pack for all you Acky fans out there! Rightfully titled the Misfit level pack, this collection includes 50 totally new levels which didn't make it into the full version of the game.
The new pack is FREE for registered players. To play the new levels download and install the level package, then in the GAMES screen click the arrow button next to the word package to change the current package, and then hit the PLAY button!
