What's your favorite DSiWare game so far?

The selection has not been mind-blowing, but I think it's actually been pretty good so far. Besides WarioWare: Snapped, I haven't been dissapointed with a game I've purchased. My favorites so far, in order:

1) Paper Plane

2) Dr. Mario Express

3) Birds & Beans

that tetris like game lol

1) Aquia

2) Birds & Beans

3) Dr. Mario Express (I suck at it!)

Nintendo needs to stop making priced game demos. Birds & Beans and Paper Airplane are just eachoneminigame from Warioware. I think the only game that isn't a sample of a game is Aquia and Mixed Messages.

1. Aquia

2. Dr. Mario Express(stink at it but it's crazy fun!)

3. Birds & Beans

4. Brain Age Express Math.
