I've been playing touchmaster and pogo island alot (aside from my every day ritual of Animal Crossing).
The DS sure is a lifesaver for those long waits!
There's a new game coming out on 2/10 called Professor Layton and the Curious Village. There's a review here
Professor Layton There are a ton of braintwister puzzles, reminds me of Azada and you can download new puzzles every week...I am so looking forward to this game and wanted to let everyone know who liked Azada and has a DS, about this game.
