It’s time for Watergirl and Fireboy to master the light. You can move different objects ( pushers, levers, usual boxes, mirror boxes )to change the light direction and open corridors. The girl needs diamonds and the boy should take rubies. If you see a green diamond try to get it first and run quickly to the doors, it’s the most valuable for your mission. You can’t touch all the liquids you see. The blue liquids are safe for blue creatures and red liquids are safe for red creatures. Don’t swim in liquids of other colours if you want to continue your journey. A, W, D and ← ↑ → will make your heroes run and jump.
