Fireboy and Watergirl in the Forest Temple/Level 3
Level 3 is the third level of the game. It is unlocked after completing level 2, and completing level 3 unlocks level 4.
This concept also introduces you to a new concept - fans. If the player is above a fan, it will push him/her up. This specific level doesn’t require collaboration between Fireboy and Watergirl, so if playing solo, you might find it easier to first get one to the door, and then the second.
