I've been playing this game now for a few weeks and have had only one crash, which baffled me, but I didn't lose data this time. (Edited later: I still crash sometimes, even when I shut down and restart the DS after each round. The last crash wiped out my MicroSD card, so it's back to the beginning...)
I wish the leader board would be culled of repeated names. In other words, I think a name should only appear once with its highest score, and all other appearances deleted. As it is now, I see the same names all over the list, on several levels (and several times on the same level) which pushes those at the bottom even further down.
