xabbusrus did do something with it , i read that at the bottom of the page,
but
i think the authors of this little game just wanted to demonstrate the similarities of
a submarine and a lever, without being to ellaborate, the three states a submarine could have in water.
positive buoyancy, negative buoyancy, and neutral buoyancy.
this could be cool in a new version of silent hunter, but i wonder when doing a lot of things manually would begin to overload
and overwhelm the players.
so far tho, my feeling is the more the better!
