0ur opinion:Item Description:Electroplankton is a truly unique hands-on visual and audio experience. Already a big hit in Japan, this is a new type of game where the goal is to create audio art. Use the DS touch screen to interact with striking underwater creatures. Poke, rub, and draw on the screen to stimulate the odd aquatic creatures and create your own music. Each level is a completely new sound experience, from haunting melodies to head-nodding beats to funky Mario theme remixes. You'll create new songs and experiences every time you play!

* A portable techno/ambient jukebox. ...
Electroplankton is a musical activity. You can pick from several "instruments" that allow you to change the tone and tempo of their sound.
lf you are looking for a unique game experience involving sound... this is for you.
A month or so later what do l do with Electroplankton? While l am programming, l plug in some headphones and listen to the audience mode for two hours or so. Any longer and my ears hurt.
Pros:
1) The game can play random sequences continously.
2) You can compose orginal music, perfect for remastering.
3) Good Nintendo style graphics
Cons:
1) Repetitive nature of game gets annoying.
2) No saving your work.

This Game Equals Musical Genius!!
This game rocks, literally. lt gives gamers a chance to create their own brand of music, to their own individual liking. This game is innovative and unique and a must-have for all Nintendo DS owners. However, if you play the game for too many days in a row, say three in a row, the game may tend to become stale, but if you stop playing for awhile, let's say a week or so, and then you play this game once again, it feels as if you are playing it for the first time again. l hope my review is able to help potential buyers out there. This game is really good.

A Distraction, but not a Game
There are 1O mini-"games" on this cart. Each one is a unique musical/visual activity.
Examples:
1. Draw lines with your stylus and the plankton will follow the path and make sounds depending on the shape of the path.
2. Record your voice and change various aspects of it.
3. Make noises and see nanocarp form various shapes.
So, in a nutshell: lt's a cool way to show off the DS capabilities, but there's no real gameplay to be had here.

ZEN plankton?
l purchased this NDS "game" because of the legacy of its creator Toshio lwai who has a reputation for experimental music programs and has collaborated with Hayao Miyazaki of Studio Ghibli fame. Electroplankton is not a game as much as a music experience. You manipulate plankton to create music. lt is never the same but it is also not what one would call a video game. You can't save your musical compositions or know what to expect when the plankton perform for you.
lt is a unique idea and it can be very calming just to listen to these A.l. creatures as they compose music.
ls this for everyone? You must come into buying this item knowing it is like nothing you have seen or heard before but also thinking of it as a sort of artistic piece rather than a conventional game. Would l recommend this to anyone? Yes, but only with to those with open minds. ls it worth the money? Yes. Should everyone buy it? No. What kind of person are you? l recommend this item highly if this makes you curious.
