They say you have to walk before you can run, and in Game Boy Works, we need to slog through some mediocrity before we get to the good stuff. Neither of these games is terrible by any means; Battle Bull feels like an update to Sega's Pengo or Irem's Kickle Cubicle, while Navy Blue 90 is, y'know, Battleship. However, both end up being let down by some questionable creative choices and frustrating technical issues. Neither lives up to its real potential.
