This update from Apple will improve the functionality of this app. No new features are included. The game will now go into "overtime" mode when time runs out. You can keep playing until the next hit from a depth charge, although ships and depth charges will continue to speed up. (Thanks to Max O for this suggestion!) 68 new enemy ships of the IJN, Kriegsmarine and Regina Marina to sink. Some adjustments to ship speeds and exposure times for play balance.
