I Have 500 Wii Points left? What should I buy?

[Magera]

I Finally bought myself a Wii points card yesterday and ended up purchasing FFCC:MLaaK - Which I think is awsome to say the least.

I'm wanting to spend the remaining 500 points on something.  I hear 'Defend Your Castle' is pretty good and it looks fun on the YouTube video's I watched but when I played it through the web browser, I did not have as much fun as i thought...  Maybe a controll thing with the mouse... as it was a little difficult to keep moving the mouse around to pick up the enemies.

Is it better on the Wii?  Should I buy this game?

OR - Would you recomend another game I could get for the measly 500 points I have left?

Thanks in advance.
