also, time elapsed, gems collected, spheres/vises spawned, appropriate-colored spheres destroyed. and something more specific like "make X combo/chain T times", "destroy X spheres at once with this particular powerup T times", "keep the spheres enough far from danger zone for enough long time" and so on
also, winConditions stacking
