Not sure what's going wrong because I didn't have this problem in the 1.4 build but in 2.0 for windows the game hangs when I get to Quentin's first area fight - battle music plays and a pair of monsters just kind of wiggle back and forth and the cards never appear, just the arrows which do light up in response to me pressing them.
EDIT: Closed the game out and re-opened it and it worked? Not sure if a one time thing or what.
