Think there is a bug on Zoe's expert level, where her voice lines do not play. Did not have that problem on easy or normal variants. Great game, though. Can't wait for more levels!
Also, seems like it overwrites high scores? I had the yellow "no misses" banner for the normal mode for Zoe, but now it says I am missing it after getting a couple misses which gave me a 4 star on another attempt.
So far, its only been the one level, Zoe's in Act 1. I have been unable to replicate it in Cathy's levels so I am unsure if its only the Normal level for Zoe. Oh well, I don't mind playing more, just figured I'd share what happened.
