Devil World is one of Shigeru Miyamoto's works. It's not an amazing game but has some things going for it. It's a great clone of Pac-Man and throws in it's own special attributes. It has a few different levels but all centered around the same idea. It's a good Pac-Clone, but in the end it's still a Pac-Clone. 

Players control Tamagon a small green dragon that has invaded Devil World (or Hell). Tamagon’s task is to collect all the  dots on the screen without being either crushed by the side of the maze (the camera is controlled by the Devil) or touched by one of the stage’s cyclops. Strangely enough Tamagon can only eat the dots when he is holding a cross. The cross also allows Tamagon to breath fire to kill enemies, but it disappears after a while and you must find another.  The game ends when you collect all the dots.

Once the main stage has been beaten you go onto a new area where you must insert 4 bible's into a Skull-Block. The enemies and screen-scrolling is still present but it is less hectic than the previous game. This is because rather than having to get every last dot which can get rather annoying if you miss one you only need the 4 bibles. When you are holding a bible you can shoot fire, but once you insert in into the skull you must quickly get another one otherwise you a in a weak position.  

The game’s confusing concept is baffling enough, but the religious items neither portrays the game’s objectives well, nor does it mesh well with Nintendo’s ‘all-inclusive’ image of the time. The obvious implication is that the holy artifacts are the eponymous devil’s weak point, but few new players would immediately realize that dots can only be collected whilst holding the Holy Cross, or that Bibles must be inserted into a giant block with a skull on it. It's poor convenience from the designer and would have been a hassle to figure back in the day. The themes of the game seem to very contrasting, especially when you get items such as ice cream as power-ups.

There's also a mini-game where you collect boxes, but it's quite forgettable.

The music, when present, is actually fairly decent – it’s got simple, catchy melodies akin to Ice Climber and the like – but throughout most of the game the soundtrack is the bleeping of the scrolling screen. The Visuals are not amazing either, the animation is fine but it doesn't stand out like Super Mario Bros or Legend of Zelda. This is the kind of game you would play for a few rounds and then go back to Pac-Man. it just doesn't leave a good enough impression on you. It can be fun at times once you "get it" but you may not want to play long enough to "get it". All in all, not amazing, but it does have some unique themes that are worth playing, but not for long.
