Touch the screen and watch thousands of particles swirl, spiral, and bloom in real time. Change the entire feel by simply changing how many fingers you use. Relax. Play. Meditate. Create wallpapers. Or lose yourself for an hour tweaking symmetry, animation modes, and effects. Uzu is endlessly deep and simply fun.
