So since I can't stop thinking about Labyrinth since I found out about the sequel, I decided to try an idea that someone else in this thread had: random party!
So I wrote a quick C++ program to determine my party, and it turned out to be:
Marisa
Alice
Rumia
Aya
Tenshi
Flandre
Yuyuko
Kaguya
Maribel
Utsuho
Mystia
Shikieiki
I just beat Alice, and it hasn't been too bad so far. Youmu has been by far the hardest due to no Reimu defensive buffs.
Lots of late game characters that have SP problems initially. In addition, I'm forcing myself to not DTH any bosses before I would've gotten Komachi, which means that Shikieiki literally couldn't do anything to bosses for the first 3 floors for fear of DTHing them.
My only heal is Rumia, so that'll be...fun. My team is abysmal at buffing, but fairly good at debuffing, which has been very helpful so far. Mystia was a godsend, and Maribel's turning out to be very useful.
My sweeping team is Aya, Alice, Mystia, and Marisa. Aya's already starting to fall off, sadly, and she'll likely stay that way until I have tons of SP.
I've gotten to 30F in previous games, but I've never beaten it, so we'll see how far I can get with this team.
