The maze is maked of colored tiles. There are two types of tiles: fixed and mutant. Fixed tiles are darker: red dark is fixed, instead red clearly is mutant and therefore for all the five colors (red, yellow, green, blue, violet). Mutant tiles change color every time that Rimbalzoid bounces over; but attention, because to every bounce the energy of Rimbalzoid is reduced! Fixed tiles are instead sure places where Rimbalzoid can stop itself to think and to rest: bouncing over the ticket remains of the same color and the energy does not come embezzled. To free gems When the gems are encircled from a blue field of energy they are dangerous!
