Submarine K-17

You have five submarines. At sea, a lot of mines ! You have to hold the submarine mines in the shelter. Be careful ! If the flashing red circle can submarine put to the shelter, if a black exclamation mark is not present ! Sorry, if you put the submarine back and where the exclamation mark-to-exclusion program closes. I work to solve this problem. Write to me, what would you like to see in the new versions. I will try to fulfill your request.
