BoxManPSP is a clone of BoxMan 2.4 for Palm OS, originally coded by CRMobilIT. The original 172 levels are included. As of this release, two more level packs are ready to download for an expansion of over 11,000 levels.
The object of the game is to push all the brown (moveable) blocks, onto the blue diamonds. When there are no moveable blocks left, you complete the level. Simple in theory, but challenging.
