I don't mind the current vent opening minigame. The only thing that bothers me is that when you accidentally click outside the borders of the minigame, it closes down and you have to start over. As for jail time reduction, idk. As a criminal, I obviously wouldn't mind it being a bit shorter. But reducing it to 2 minutes tops would make breaking people out pointless, because it takes at least a minute starting from getting inside the interior to leaving with your friends, and it could only take longer if one of you gets arrested in the process. So that would make quick jailbreaks meaningless, unless there is a bankrob going on and every second matters.
