Yop the boss fights crashed for me every time, after few rounds.
Damn I love the music in this game. The even music this time around is very very nice. To bad it switches once you arrive at the lvl Boss to that crap tune.
I honestly hope - since music is a HUGE part of this game - that they´ll have a BGM folder added to the game eventually with all the soundtracks from both normal game and all the events up to that point and onwards. I can see myself listening to some of that stuff from time to time.
