I've managed to get all trophies and the most annoying one is probably all gold prizes. You have to do all stages (normal and arrange modes) in all difficulties (easy, normal and hard).
Getting the new endings was so random. I don't even remember how they pop'd up.
All others are pretty much the same except for the new characters you have to save and Rin's path. But that's it.
Glad I am done with it (and with Axis Mundi too haha). GL to ppl trying to plat this game ^^
