Review
Zoop is a game that will test not only your eye-hand coordination but your brain power as well. At first glance, it looks so easy. All you've got to do is shoot the right colors to keep the shapes out of your space, and since you've known your colors since you were two years old, you'll think this game must be child's play. Adding to your misguided belief that you will beat this game in one or two sittings, it is very easy to learn how to play, but the simplicity stops there. Like the old story about the boy at the dike who tries to plug up the dam when it keeps sprouting holes, it's only a matter of time before one of the shapes enters your territory, effectively ending your game. You won't find any continues or level saves here, so be prepared to lose a bunch of times before you make it very far into the game.
Zoop for the Genesis is very similar to Zoop for the Super Nintendo with one overriding exception: The controls aren't as good. Sometimes when you try to point your triangle upward to shoot, your aim goes off to the left or right. Neither game has great controls, but the Super Nintendo control pad, which is generally a better controller to begin with, is much better suited for a game of this type. Even so, you'll have a good time playing either version.
This is a fun game, but there's one thing that might improve it. What if, in later levels, the Center Square turned into an octagon, and the advancing shapes began coming at you from eight directions instead of just four? Wow... Oh, well, it's probably better that the designers left well enough alone. If they would've tried and jazzed this game up too much, they might have detracted from some of the things that make it so appealing. There are enough games on the market already with dazzling graphics and limp game play.
If there's not a 12-step program for those of us addicted to Zoop, there ought to be. Like Tetris, it is a deceptively simplistic game with very few rules, a clear objective, and no secrets or surprises. And like Tetris, nothing short of your house catching on fire will pull you away from it.
Graphics 
The graphics are plain and simple, but amazing graphics are not why you play a game like this.
Sound 
The music, which sounds like bells, drums, and a bass guitar, has a clear and catchy beat.
Enjoyment 
Even though this game is plagued by substandard controls, it's still a lot of fun.
Replay Value
Although limited in nature, Zoop is incredibly addictive, however, a two-player mode would give this game even more added life.
Documentation
The instruction booklet is very basic, as it should be. There doesn't seem to be a whole lot of other information about this game.
