On a system that's got a boatload of support and an established library (GBA), sure, but not on the DS, which hasn't had a release since RRDS IIRC, and only has a couple of games upcoming this month and the next.
Its brilliant. I got the game quite cheaply just before Christmas from play asia and have really enjoyed it. The 100 puzzles get quite difficult later on so you'll be scratching your head at some of them weeks after purchase. The hectic Tetris like challenge mode is alos fun and you can even make your own puzzles and give them to friends using a code. A bit of a gem in my opinion. Well worth a look if you like puzzle games or are after something a little different.
Whoot! This is one of the ones I wanted to come over. I do believe it's the game that was recently described as being as 'addictive as popping bubble wrap' or some such.
