There's surprisingly little variation between levels, particularly in Story mode where stages are strung together by means of a threadbare plot that abruptly ends. Changes in the shape of the pens and wind speed are cursory variations that don't entice replay.
Customisable avatars and llamas, unlockable multiplayer ranks, even just adding in different terrain would weave in the variety needed. Nevertheless, Fleeced! has an uncanny way of making you forget about these shortcomings by sheer virtue of its creativity and fun gameplay.
