This game was TERRIBLE. The gameplay involved you scraping across the DS repeatedly to make Pikachu run, and it pretty much singlehandedly destroyed my original DS' touchscreen.
This was very much a game from the launch period of the DS where developers were trying to figure out what they could do with touch controls, and this experiment did not turn out well.
There was a kind of neat feature where you could import your Pokemon from the GBA games to turn their sprites into racecourses though.
I'll defend this game, the move mechanic is kind of dumb but it's only destructive if you let it and the rest of the game is a really weird, cool design for a racing game. You essentially have to scope out your next path/destination yourself, and playing multiplayer is a one of a kind experience with everyone ballooning up and skydiving around huge maps.
