"The original Bomb Jack was an addictive little arcade game in which the objective was to collect all the bombs in each level while avoiding enemies. Sounds like a simple concept - and it was.
For the NES, though, Tecmo decided to make a sequel with a bit of an adventure game element to it. The bomb rooms from the original game are still here, but they only really make up a small part of the game. Between each bomb room is a long hallway, tunnel, or what have you, filled with treasure chests and enemies. While you can just rush towards the exit, this game has a metric ton of secrets, including several hidden levels, and not just in the chests - so if you truly want to beat the game 100% you'll have to jump around in very inconspicuous spots until you find the goods.", writes NintendoLife.
