I really like how the HUD looks this time, very colorful, yet not as busy as LoLK's.
I have to say, I don't like seeing the 0/3 and 0/5 life/bomb pieces, but who knows, maybe we'll get something else from that now, probably related to that corner gauge. I wonder how the overall difficulty will turn out with going for a "simpler" game this time (but hey, Spell practice is back, that's something), though I really don't expect precision dodges to come back full force after Junko.
Cirno being the summer character is certainly an odd one, and she's brown now, so fanart is
probablydefinitely exploding over that right now, I wonder how she will work now. And Aya is a really nice addition imo, gotta go fast. The secondary options thing looks interesting, and Marisa's layout reminded me of he DDC flamethrower, with her being winter-themed, maybe we will see Cold inferno again (a.k.a. the best shot Marisa's ever had).
