Ah, Mappy. This is the very first game I have ever played. I played it when I was like 6 or 7 on the JAKKS Pacific. Heck, I still have the Plug & Play for it. This game is really fun. Mappy is a game where you play as a police mouse and you have to retrieve the stolen treasure. The game was a charm for me when I played it again on MAME.

Graphics
Many games on the arcade did not have understandable graphics back in the early 80s. However, Namco games were games with quite good graphics for its time, and Mappy was not an exception. That is why I give it a 9.

Sound
Oh.. The music.. How I loved that music. The music was great, especially for its time since most arcade games had no music. I don't have much more to say about it, but it deserves a 10.

Addictiveness
This game is addicting, has endless gameplay, and a great family game for competition. There are 16 different possible level designs, looping infinitely. Competing for the highest score is better while trying to collect the items in order for increased difficulty, but higher scores.

Story
The story is simple but entertaining. Mappy, the police mouse discovers many, many houses with stolen goods. The cat boss (GORO), has the "cat burglars" (MEWKIES) steal goods. Mappy has to get all the stolen items without being killed. Pretty good story for an Arcade game, so I give it an 8.

Depth
This game takes approx. 3 hours to go through 256 levels (16 loops of every level design), and after 256 you go back to level 1 again. Three hours makes a pretty good time for an arcade game. Technically, however, this game is endless. For depth, I give a 9.

Difficulty
The game is not difficult.. at first. However, at level 10 and on, levels get really hard. I give the difficulty factor a rating of 6.

Overall - 9.2/10

The game is really fun, addicting, but the levels are a little bland. This was my review for Mappy. Ciao!
