My original comment when the countdown on the website went up was to ensure it's kept as adult content. There can be a family mode option or whatever, but I think it's crucial that it keeps the same 'language' and themes of the movie to really capture the right atmosphere.
One little thing they could put in is something similar to ST:TNG where Donny tries to make a comment when you lose the ball, and if you press both flippers at the same time Walter says "Shut the fuck up Donny".
