Nightfox has a new DS homebrew game for us all to enjoy. It's called Codename: Puzzlemania - Alpha, and it's a collection of minigames.
Right now, there are two mingames available, both fully playable for the skilled and left-handed. Gameplay appears to be simple. It looks like you'll just have to solve the puzzle (of kawaii anime girls) on timed mode. To escape the game, just press SELECT and you're good to go if you don't feel like playing anymore.
