An old 2D japanese game which had a scientist who gave us some missions to go to different places and had 3 main characters that looked like spheres with a pair of hands and legs. one of them was a pink sphere with a dark blue heart as its face, carring a yellow whip as a weapon, the second one was a blue sphere shaped character and a yellow circular face, i belive that the third character was a greenish sphere but i cant remember the details anymore; each character had its own special weapon.
PS:
I've been searching for this game for a long time but because it was my childhood computer game, i cant remember its name, please help me out to find it again; Thanks!
