Fun game! Wish the full cart version was available in the U.S. One issue to bring up, and I was wondering if anyone else had this problem. I was about 80% complete and booted the game up. I continued playing where I left off and noticed the main menu music was still playing over top my current levels music, drowning out the sound effects/music, etc. I rebooted my DS, tried to start again, and it continued screwing up. I backed out to the main menu and the music kept layering over top itself. It sounded terrible. Tried playing one more time and the game and DSi locked up. I couldn't even turn the power off. I ended up having to do a soft reset to get everything to come back. Hopefully my save file is corrupt and this isn't a bug in the game. I will try starting over from scratch with a new save file, and see if the issue pops up again.
