Thanks, it's addicting. I'm at floor 3, level 11 and synthing everything on the way up. I can beat most songs on Heavy in DDR, but I have to play this on Medium 'cause there's so much going on.
Couple bugs:
I set the difficulty to Hard when I first started the game, and it seemed to stick me on Easy. Changing it mid-game fixed this.
I also adjusted the text speed during the beginning cutscene to 5, then 4. When it was 4, Ky's speech didn't appear for a while at first.
