Cool Cool Jam is a
In Cool Cool Jam, your object is to form a band. You can choose between a boy and a girl, and from there on you walk through town, jamming with villagers and ‘Men With Hats.’
If you do well, you get pieces of instruments. To jam, you first have to please people by clapping to a certain tune.
Each instrument requires you to hold your NGP in a different position, and the controls are different for each instrument. To play the guitar, for example, you have to hold your NGP upside-down. The strings are controlled with the two buttons, and you pull them with the joystick. You have to pluck the strings when the matching color reaches the respective string’s end.
