What is Fireboy and Watergirl: Forest Temple?
This is the first game in the Fireboy and Watergirl series, created in 2009 and remade in HTML5 in 2018. One player controls Fireboy, the other controls Watergirl, and you solve platforming puzzles together to collect colored diamonds and reach the exit doors. You can also play solo by switching between the two characters yourself.
Controls for both heroes
Each hero has separate controls so two players can share one keyboard.
| Hero | Move left / right | Jump |
|---|---|---|
| Fireboy | Arrow keys | Up arrow |
| Watergirl | A / D keys | W key |
Hazards and element rules
The puzzle design is built around a strict set of elemental rules that you need to keep in mind on every level.
| Hazard | Fireboy | Watergirl |
|---|---|---|
| Red fire pools | Safe | Deadly |
| Blue water pools | Deadly | Safe |
| Green poison goo | Deadly | Deadly |
Collecting diamonds and reaching the exits
Each level scatters red diamonds for Fireboy and blue diamonds for Watergirl across platforms. Neither hero can collect the other's diamonds, so teamwork is essential. Once all diamonds are gathered, both characters must step onto their matching exit doors at the same time to complete the level.
Tips for clearing tougher levels
- Separate early: figure out which side of the level each hero owns before you start moving.
- Use buttons and levers: many platforms only move when one hero stands on a pressure switch while the other crosses.
- Green goo is the equaliser: neither hero survives it, so plan routes that avoid it entirely.
- Play solo by pausing one hero while you move the other across a dangerous gap.
