Topic: Scribblenauts keeps freezing.

I had originally posted this in the DS section, but I thought it would work better here. Anyways, I got Scribblenauts brand new from gamestop, but it keeps freezing. About every 5 levels, it will freeze and I have to turn my DSi off. Also, sometimes it starts lagging really badly. Anyways, is there some way to fix this, is it common, and if it's not something I did wrong, is it worth it to try and return it?

It happens to me all the time. I think that it's just the game.
