Then you have a lot more to do in the game. Here's what my quest log looks like near the end of the game:

As far as whether the game is finished, I think it is. v 0.14 was the last version released, and I think it was supposed to include the last part of the game's story. However there's a bug that causes the game to freeze after you speak to the ship captain and get transfered to the next map, so actually finishing ti is impossible. However, you can still do all the other quests before that, so plenty of content for you to do.
If you can't find where to go next, post your save here so that I can check (it's been a long time, so I don't remember most of the game).
