Okay, guess I'd better post here now that I've got that Normal 1cc.
Stage 4 was meh, there wasn't really enough going on. Music was awesome, but it always is. Murasa was a decent enough fight until Sinker Ghost (?) at which point things started getting a little retarded.
Stage 5 is godlike. Awesome stage, awesome music. Syou is entertaining enough and has a great kinda sinister theme that ZUN doesn't do a lot. (My only complaint is her third card which is sort of whut.)
Stage 6 - nothing sets a scene better than a heartbeat. Stage 6 music is beautiful, stage is basically 'Hey have these UFOs you're gonna need them'. Byakuren is another fun fight, and again the music is amazing.
Extra from what I've seen is very meh. The stage is alright and the boss is fun, but Kogasa midboss is really irritating. I'll probably grind a clear in the next few days.
All in all, actually much more entertaining than I expected to be. Wondering what people are going to do with these characters and waiting on a translation.
In other news, ABSOLUTE JUSTICE
A balanced diet of red and green UFOs should be good enough for 1cc.
I just farmed red and got to max lives by Stage 4 on Normal.
