Uber-Boat (Unhacked Version)

Game Information
You are in control of a destroyer and are being attacked from submarines below. The submarines will be deploying mines that will float to the top and will slow down your progress. You have 90 seconds to destroy as many of the submarines as possible, but will gain extra time if you can reach the target amounts! Destroy the submarines by dropping depth charges from the front and back of your ship. Note you can only drop 6 depth charges at any given time.
