Short and dull. This game's "novelties" are tapping frantically at the screen and tracing over lines. No thinking required. The graphics are good in a stylised kind of way. That's all I can say for it.
It's so darn stylish and such a great demonstration of the DS hardware. Unfortunately, it's over long before I want it to be, and there's not enough to keep me coming back to it after a few more rounds with it.
If you are a big fan of mini-games, you're planning on buying a bunch of games this month along with your DS, and would like to pretend that you actually have a girlfriend... then I suggest you go pick up a copy of Feel the Magic: XY/XX.
