To move Watergirl, use the A, W, and D keys, and to move Fireboy, use the arrow keys. Because fire and water do not mix, keep Fireboy out of the water and Watergirl out of the fire. Now that you understand the controls, let's go over some useful tips and techniques.

Avoid the green lake.

This one is quite simple; we know that as elementals, fireboy and watergirl can only travel on fire and in water, but what about the green lake? Both Fireboy and Watergirl must avoid the green lake. Remember that if one of the characters dies, you will have to restart.

Work together.

It may be tempting to go forward with one character and attempt to complete the level with them before moving on to the next, but there are many levels where this is just impossible. To go through certain stages, you must employ both characters to activate switches and buttons. Make careful to employ Fireboy and Watergirl together to help you complete each level.

Study the Level Before

One useful advice is to study the level before attempting to beat it. Take a moment to glance around the level and see what obstacles are in your path. Take notice of the "danger" locations or those with green lakes. Once you know where all of the obstacles are, you can begin to plan how you want to complete the level. Taking a moment to review the level beforehand may help you beat all of the levels.

Play with a friend!

Playing with a buddy might be an excellent approach to complete all of the levels in Fireboy and Watergirl. One player can control Fireboy, while the other can control Watergirl. This divides the elemental duo's workload in half, allowing you to concentrate only on one individual. Plus, who doesn't like playing games with their friends?
