This game is so broken, it even breaks your DS Touch Screen.
The gameplay is very terrible. You can only be Pikachu, the entire game is repetitive, the challenge level is mega-low and to play the game, you keep on rubbing the Touch Screen with the stylus over and over again. Of course, doing that too many times can cause the Touch Screen to break. That happened to my old platinum DS, and THAT'S why the gameplay is so bad.
The graphics are also mediocre. Sure, there are 3D Pokemon (which is good), but everything else is choppy. Besides the 3D Pokemon, the game looks more like a Super Nintendo game. The graphics are so bad, they aren't even funny at all.
The sound is also the worst. Sure, there are other sounds, but most of the time, you'll hear Pikachu yelling out "PIKA! PIKA!" over and over and over again. This is very annoying, you'll want to turn off the DS's volume.
There is absolutely NO replay value to all gamers, even to hardcore Pokemon fans. Even after completing the first track, you'll want to turn off the game.
Final words: This game is absolutely bad, it's even worse than Nanostray (which was also bad). The game is very easy and repetitive, playing the game can break your Touch Screen, the graphics are terrible and the sound is very annoying. Seriously, do not buy this awful garbage, even if you are a Pokemon fan, as this will malfunction your Touch Screen.
