Sam's game was our only game to use a +/- scoring system as we felt we needed to mix things up so it wasn't too easy to play. I mean hey, we don't want everyone winning! Using the up and down arrow keys you must position your 'fishing hook' so that you get the most points by collecting either the yellow duck (10points) or the ugly duckling (20points as they are rare!) which swim across the screen to the left.
The user must be careful to avoid the rubbish in the water as well, as getting any of that on your hook will result in a points reduction (-10points). This must all be done within 60seconds to get the most points possible.
This game works very well and the possibility to add level based gameplay could also be implemented to this mini game if more time was available.
