It`s for the contest. I just made the ship, not scene.

To start, press enter. Then, to sink the boat, press "down", and if you want to go up, press "up".

If you want to move front-thing, use "1" (numpad) and "2" (numpad). To move conveyor belt press "4" (numpad) and "5" (numpad). It`s usefull when unloading.

With this ship, you can catch all of the fishies on this scene.

PS: If fishies get stuck when unloading, try to shake the ship with "up" and "down" keys.
