Continuity mistake: Mr Freeze's ship just appears out of the clear blue rather than having been anchored all night when you can play "In from the Cold."
Batman: I am vengeance. I am the night. I am Batman.
Trivia: When Batman enters the clock tower, there's a flashback scene of Barbara being shot by the Joker. Before this occurs, go to the back wall and zoom in on the movie poster, "Dark Interlude." One of the names on the poster is Matthew Hagen. In "Batman: The Animated Series", Matthew Hagen was an actor who was transformed into the shape shifting villain Clayface.
Question: Except for Two-Face, Killer Croc, Scarecrow and Jervis Tetch, why were the rest of the villains redesigned?
Answer: Probably because different people were working on the game. Scarecrow and Croc also have different looks if you've played Asylum, City, and Origins, they look different here too.

Croc's redesign is easily explainable as it's revealed in this game that his mutation is accelerating.
