under the ocean getting gems

[Chii!]

help! Im stuck, Im looking for the last gem and the boat isn't moving. the games seems to be running fine but I can't click and have the boat move anymore, and I tried to close the game and restart from my save point. why won't they let you move with the keyboard instead of the mouse?! I will not have to start the game over, there must be another solution. crud. or does someone have the game completed and can give me a save file or something? thanks!

I have the opposite problem. I picked the difficult setting which makes the submarine follow strong currents. As a result I lose all control of the submarine when trying to get to the last crystal. I know where it is, I just can't reach it.
