Len'en 3: RMI Easy Mode but I Try to Constantly Move Yabusame and Tsubakura to the Beat of the Music
Since characters don't switch unless you bomb or die, Tsubakura didn't actually end up doing anything until around halfway into the video. :b
I ended up doing this not long after doing it for the second game. Mainly because doing this challenge would also unlock Shrine Team for the extra stage. I had them unlocked for the extra stage previously, but that was somehow reverted when I applied the English patch.
I'm a bit more familiar with this game's stage themes compared to the first two games, mainly because I've played this game more. Still not that familiar with them though.
I'm debating whether or not I should do this for the fourth game. I hate that game's stages, but maybe it won't be so bad if it's on easy mode. Either way, I definitely won't be doing it for the neutral route. That entire route has like two stage themes total throughout the whole thing.
