 * Character : kid/balloon
 * Theme : flying in a balloon
 * Concept : 'How much the kid has to walk to get to the balloon?'
 * Represent fractions as : circles/arcs
 *
 * Game modes can be :
 *
 *   a : Player can place balloon position
 *       Place balloon in position (so the kid can get to it)
 *   b : Player can select # of circles
 *       Selects number of circles (that represent distance kid needs to walk to get to the balloon)
 *
 * Operations can be :
 *
 *   plus : addition of fractions
 *     Represented by : kid going to the right (floor positions 0..5)
 *   minus : subtraction of fractions
 *     Represented by: kid going to the left (floor positions 5..0)
 *   mixed : Mix addition and subtraction of fractions in same
 *     Represented by: kid going to the left (floor positions 0..5)
