DSiWare (ideally Action/Platformer) Reccomendations

[Vectorferret]

So, I'm going to be getting a DSi XL in a few hours (since I rarely take my DS portably when I don't have a large backpack). I already have DS cartridge games, so I am good on that front. What I'm wondering is what sort of action or platformers (or really any DSiWare) games I should be looking at.
