Mighty Bomb Jack

Each level is split into two parts; an action zone and a Royal Palace room. The mechanics and level designs of the Royal Palace rooms are directly lifted from Bomb Jack. Action zones can be split up into several portions and contain power-ups usually hidden in treasure chests such as money bags, Mighty Coins and Mighty Drinks. Mighty Coins allow Jack to change colors; blue allows Jack to open orange treasure chests, orange allows him to open any treasure chest by simply touching it from the side, and green transforms all enemies on the screen into coins for 5 seconds.

Mighty Drinks add 10 seconds to the game's timer. Secret passages can also be found in the action zones, activated by finding a Sphinx in a visible or hidden treasure chest.

Jack, the protagonist of the game, must make his way through 16 levels set within a pyramid in order to defeat the demon Belzebut and rescue the royal Pamera family.

The game was directed by Hideo Yoshizawa. It was his debut title as a game director.

Within PAL-A regions, the NES version was only released in Australia.

In Japan, the game sold over 1.5 million copies by 1987. It was Yoshizawa's biggest commercial hit up until its sales was surpassed by Ninja Gaiden.

In North America, the game received a positive review from Computer Entertainer upon release, with a score of 7.5 out of 8 stars, the same as The Legend of Zelda in the same issue. They called Mighty Bomb Jack a fast-paced "adventure-action game" that is "loaded with nuances which you will continue to discover as play" and said it was a tough, frustrating, "just one more time" game that "will have you back for more and more!"
