beta version 3: jumping shadows on the ship plus moving wafes

If you scroll the screen a bit up and down in the right position, the shadow of the ship jumps from one image to the other.

The game is paused.

If you are in the upper part of the map (first image) the shadow of the ship remains constant, as it should be.

If you scroll down to the lower part of the map (lower image) and you scroll around, the shadow of the ship changes a lot depending on your position.

Expected behaviour:

The shadow of the ship should not jump or move at all when the game is paused.

The only reasons why the shadow may change are:

- The ship moves because of the waves.

- The ship or parts of it ( like the sails) move because of wind.

- The sun changes the position over the day if you wait long enough.

The game is not a physics simulation so it is ok if the shadow of the ship is constant, but those jumps feel really bad.

The wave caused by the ship changes its direction relative to the ship when you scroll the screen up or down.

The game was paused while I made these images.

expected behaviour:

The wave caused by the ship should always have the same position relative to the ship unless the ship is moving or the direction of wind or waves changes. Because the ship does not change its direction while you are on this screen, the wave caused by the ship should always have the same position relative to the ship.
