Really two games in
One cartridge, Namco's somewhat-hard-to-find Dig Dug
for the classic monochrome Game Boy offers not only a decent port of
the arcade version, but throws a dandy original bonus game into the
bargain. The primary draw, of course, is Dig Dug, and since Namco
originated the game, they know what they're doing: despite some minimal
scrolling (similar to the Game Boy edition of Pac-Man) required by the
small screen, it's an almost-perfect rendition of it's coin-op cousin,
with one possible exception -- it seems like your burrowing enemies are
actually meaner in this version.
