Can Fireboy and Watergirl enter the same exit door at the same time?
No. Each character should enter the exclusive one: Fireboy should enter the red door, and Watergirl should enter the blue door. The level is only completed when both characters successfully enter their respective doors. The order doesn't matter, but both must complete their exits.
Why does Watergirl slow down on snow? Can't she run faster?
This is a game mechanic. Snow surfaces inherently slow Watergirl down.
Where do you restart after failing a level?
If either character touches water, fire, or green slime, the entire level resets immediately. You restart from the beginning. There are currently no mid-level save points, but most levels are designed for quick retries.
Can I play solo? Or are two players required?
Solo play is fully supported! Use the arrow keys to control Fireboy and WASD for Watergirl. Of course, two-player co-op is also available—each player controls one character for smoother real-time coordination.
