A new more realistic human character has been added as the default character art but don't worry, you can still choose the original character if you prefer the more humorous looking character in the main game settings.
Other changes include the ability to customize the appearance of players in the Workshop selection, choosing skin tones, (limited) hair / facial hair options and hair tones.
The player characters default speed has also been increased by 10% to allow for a more frantic pace bringing it closer to the speed of games like Sensible Soccer.
Note: Game Speed can be tweaked in the Setting screen giving options 70 - 110% so you can choose a game speed to your liking.
