gbadree from the PAlib forums has released this NDS homebrew port of a classic Japanese puzzle game. Created in 1980 by Hiroyuki Imabayashi, the challenge of Sokoban is to push (never pull!) boxes in a warehouse to their correct positions. You know, sort of like FedEx and UPS - though they never had to contend with 360 levels of box-pushing split between two chapters, as it is here in dSokoban.

Controls are fairly simple: you control your warehouse keeper with the D-pad. Undo any screwed-up moves with B, restart a completely screwed-up level with X. On bigger maps that don't fit into the screen, use L and R to scroll the screen. Start to retrun to the title screen, and Select to change the BGM - but you have to unlock the feature first by beating the first stage!
