has a grass-like image, while the playing area,
the pond is surrounded by the grass-like objects.
From levels 4 to 8, the pond has small islands
of wall objects behind which the ducks can seek
shelter (they are programmed to do so). The ducks
swim in the pond which is made of water like
images. The only function of the wall object is
to stop the ducks from moving out of the pond.
The duck object, which has the image of a duck,
moves with varying speed. Whenever it hits a wall
object it bounces. The player can shoot through
the walls on levels 4 to 8, but the effect of the
shots decreases. Whenever the player hits a duck
the score increases 10 points. The duck's speed
increases slightly when it jumps to a random

place. The gun object is placed at the bottom of
the screen, where it is fixed and can only move
to the left and right in a half circular pattern by
keyboard commands (See Controls ).

Sounds

We use 24 sounds in this game, covering all the
categories from the IEZA-framework as well as
the span from encoded to embodied sounds (see
Table 4). In addition, the sounds are spread across
the action versus setting axis and the diegetic
versus non-diegetic axis.
