The most enjoyable puzzle game I've ever played!
It's a very unique puzzle game which I've never seen before. You have to use the stylus to move Meteos' up and down to match them with other Meteos' which are the same colour (type) for them to launch. Making things unlockable makes the game even more entertaining. And it's a very challenging game for people will slow reaction times. So playing this can also practise your reflexes.
The single gameplay can be a little short for some people, but with its online multiplay makes it last longer. And it's fun to challenge other players around the world, testing their reflex skills.
The disappointing bit is that the graphics are poor, but because this isn't a good-graphic-needing-game, it's still alright for it, it's also a 2D game, so it doesn't matter.
Anyway, it's a game that any DS owners should have... can't be bothered to write more...
