You switch between controlling Fireboy and Watergirl by pressing the arrow keys or WASD. Use the left and right arrows (or A and D) for Fireboy, and the up and down arrows (or W and S) for Watergirl.

The main objective is to guide both Fireboy and Watergirl to the exit of each level. You need to use the lights within the Light Temple to your advantage and work together to overcome obstacles and solve puzzles.

Fireboy cannot touch water because he is a fire-based character. Any contact with water would extinguish his flame, making it impossible for him to continue the journey.

Watergirl cannot touch fire because she is a water-based character. Any contact with fire would evaporate her, preventing her from completing the game.

The lights in the temple allow you to change the environment to suit either Fireboy or Watergirl. For example, you can use light to create platforms for Watergirl or to extinguish flames for Fireboy.

If one of the characters dies, you will need to restart the level. Both characters must reach the exit together, so you should be careful to avoid any hazards that could harm either of them.

Unfortunately, there is no built-in save feature in Fireboy and Watergirl 2: Light Temples. You will need to complete levels in one session without interruption.

Yes, Fireboy and Watergirl 2: Light Temples is compatible with mobile devices. You can use your touch screen to control the characters by tapping on the screen to switch between Fireboy and Watergirl.
